Furnace Error Codes

Green Flashes 
One green flash signals normal operation with no call for heat, meaning the thermostat is not currently telling the furnace to produce heat. 
Two green flashes and three green flashes may appear after attempting to retrieve any stored error codes, and both signal that there are no error codes stored in the memory system. 
A rapid green flash is only used during factory testing. If this code occurs, turn the furnace off and then back on. 

Amber Flashes 
One amber flash signals normal operation with a call for cooling, meaning the wall thermostat is currently telling the furnace to cool. 
Two amber flashes signal normal operation with a call for heat, meaning the wall thermostat is currently telling the furnace to produce heat. 
Three amber flashes signal normal operation. The wall thermostat temperature has been fulfilled, and the furnace burner is ending its cycle. 
Four amber flashes signal that there may be a restriction in the circulating air system that is reducing the heating capability of the furnace. 
Five amber flashes signal a restriction in the vent or combustion air system that is reducing the heating capability of the furnace. 
A rapid amber flash signals a possible low flame. A common cause for this error code is a dirty or incorrectly positioned low flame sensor rod. 

Red Flashes 
One red flash signals that a flame is present but that no power is being supplied to the gas valve. Possible causes for this might be a gas valve that is leaking gas to the burner or that is closing too slowly. 
Two red flashes signal the pressure switch is stuck in the closed position. Possible causes include incorrect pressure switch wiring or a faulty pressure switch. 
Three red flashes indicate the pressure switch is stuck in the open position. Possible causes include blocked vent pipes, blocked air intake pipes, faulty pressure switch or pressure switch hose or a faulty combustion air blower. 
Four red flashes indicate that a 24-volt fuse or the high-limit switch is open. Possible causes include an improperly sized ducting system, a dirty air filter, a faulty blower motor, an open fuse on the control board or restricted circulating airflow. 
Five red flashes signal that an auxiliary limit switch or a rollout switch is open. The rollout switch (on the side of the burner box) is a manual reset switch and you reset it by pressing the button in the center. 
Six red flashes indicate a current failure on the modulating gas valve. 
Seven red flashes indicate the furnace has entered lockout mode because of no ignition. The furnace control will attempt to ignite the flame three times, and if unsuccessful it locks out for an hour before retrying.

I’ve lived in my house for 25 years now. The old ac had been around for about the same time and had gotten slow over time so I had to replace it. I bought York because my son recommended it to me and so far I like how it works. It is so quiet and does not need to stay on for long to cool the house properly so the utility bill also remains at a reasonable figure.

My furnace installation went as smooth as could be for having my whole unit
My furnace installation went as smooth as could be for having my whole unit die a few days after Christmas. It's quiet and efficient, and seems to be working out beautifully. It's heating my 2600 square foot home that was built in the 1860s. My bill has not gone up at all and I turned the thermostat up higher than I had it before. The unit is much much smaller than my old one too, which is a nice bonus. I'm very happy with the financing and payment schedule offered also.

I bought this house less than 5 years ago. York Split System 2.5 Ton Heat Pump was 2 years old when I bought the house. In less than 5 years, 2 motors, filter dryer repaired, 5 times called for Freon, after 5th time they found the leak…Condenser Coil. Been waiting 4 weeks for “delay in parts” without air conditioning…in FLORIDA and they cannot tell me when they will receive them. Have had 4 different technicians, all of which told me getting parts for YORK is not easy. Who has time for this!!!

I installed a York Affinity heat pump at my cottage, and it has not worked
I installed a York Affinity heat pump at my cottage, and it has not worked at all in the two years since it was installed. Virtually every part has been replaced and my power bill was over $9000 year to year. Keep in mind that the cottage is not occupied during the winter and the temperature is kept at 50°F. The consumer relations support center has been a useless waste of time and has only served to increase my frustration and anger as a result of having this piece of absolute junk installed at my house. DO NOT buy a system from this company. I cannot stress enough how poorly my system has preformed at my cottage.

I am happy with this purchase because after buying a few appliances that kept breaking down I sort of got used to poor quality. York, however, has changed my perception of these brands. If you take your time to do your research on what you want to buy then there is very little chance of being disappointed. Thanks to York my house is comfortable again.

I had a York Affinity 8 series installed in 2011 in southern California (i.e. it doesn’t get heavy use). I had the system maintained annually by professionals. In year 4 the system failed to kick on. It was identified that 3 different parts had failed simultaneously. While the parts were covered under the warranty, labor to replace the parts cost 25% of the original unit price! GASP! I called York several times to see if they’d do anything to offset such a high cost as this points to poor quality and potential for future problem, but they repeatedly declined. Buyer Beware!

York air conditioners are durable, reliable, and built to last. The company has a number of excellent entry-level cooling systems for people who are on a tighter budget. Even their premium line of air conditioners is still quite affordable, making York an excellent brand if you want to upgrade to a newer and more efficient system without having to spend a lot on a new air conditioner.

We replaced our old unit (Rheem) after 10 years because it failed. We chose a York as a replacement because they offered the longest warranty on parts and labor and because it is the brand our contractor recommended. It has been installed for about an hour and is currently working great.

I live in Kentucky, and had a York air-handler and heat-pump installed at our home in January 2017. I used a “family owed with family values” company to install this air-handler and heat-pump. We spent around $8,000.00 on the install and upgrades from our old “oil furnace” to this new system.. We have had some very cold weather this year, and we have had SEVERAL issues with this new system. In the past two months alone I have had a service tech at my home 6 times, because the system is just not working! The heat-pump won’t run I show on aux heat, but it’s blowing cold air. After having service techs in and out of the house the past few months. I have heard so many stories from these techs about what the issues are it’s becoming ridiculous. One guy was actually here for two hours to tell me there a “wire had come loose” REALLY?? NO IT DIDN’T! Two days after the guy “put the wire back” cam. I had to have someone else come because guess what… you got it the system wasn’t working! The next person came(who by the way is the only person I think who knows anything at all and he is just a service tech they better keep ahold of that one!) told me that the heating elements were completely burned up all three of them, and that they were not working, and probably had not worked in a few days! This “part” was replaced on 3/27/18. Then on 4/16/18 the system again has stopped working! I called the service company on the Sunday 4/16/18 it was 34 degrees outside by the way, and the response I received from them and there 24 hour emergency call center was to turn on my emergency heat! YES my emergency heat that cost a small fortune to run! After a short argument with the owner he then advised me that they would NOT come and fix the furnace because of the argument over the phone! The reason for the “argument” was because when I spoke to the owner of the shop he started telling me that they have NOT been to my home a-lot! (I guess 6 times is not a lot in 2 months it is to me, but I guess we have different standards!) He then told me that I had gone a “good year” before they ever had to come to my house! (which by the way is completely incorrect!) Seriously! I am not sure what kind of companies I am dealing with but as for what I can tell right now the YORK system and the company I picked to do my work are both “failing” I would never recommend this SYSTEM nor the company I had install this system! (which I would not name on this site as I feel it’s not professional!) Has anyone heard of any recalls on an electric system what is this about a lawsuit, is that just for the gas systems? I am going to try and contact York personally to address my issues with the system to see if they have anyone they recommend to come out, and take a look.. I am sure this will fall on “deaf ears”, but I have to do something I am completely frustrated with all of this! I am interested in this “lawsuit” and the details to see if this is something that may be going on with my system as well.

It’s surprising how many people are complaining about York air conditioners. I feel bad for them because it must be a problem with the installation. I read about the problems that can be caused by poor installation online and made sure I got someone who could be trusted with the job. It’s 2 years down the line now and nothing is the matter, the ac functions just as well as it did when I bought it.

I have had my York ac for 2 years now and the unit is still functioning well. I read some reviews about the ac on the internet and there we a lot of people complaining about the company’s quality. Well, I am here to tell you that York makes good HVAC systems and I can vouch for them any day.

I have been selling and installing York/JCI equipment for decades. We have installed thousands, and as an authorized dealer, we are trained by the factory and stay on top of all the new equipment install requirements. Our warranty program is in two parts. 10 year parts, which does not include labor costs, and then part two is offered at a small additional charge, which includes parts, labor, and anything else needed to make the repairs or replacement of the faulty equipment. When installed properly, these unit simply do not have problems. Out of over 5,000 systems we have had 4 actual warranties, which is an unheard of low percentage industry wide. Each contractor is obligated to explain the system warranties and what is available to them to be sure to have all the correct information. Each review I have seen on this system is of issues that were avoidable if installed or managed correctly by the dealer. True York dealers that do the job right just don't have these issues.

Check out the top ten furnaces on this website and as of today you will see that the top 3 furnaces (they list them in reverse order from #10 to #1) are all york brand. If it is important to you to buy a product that is built here, York is a good choice. Their high efficiency models start at 95 afue, and that is a great efficiency at an entry level price point. The two-stage high efficiency furnaces offer increased comfort, and there are models throughout the line with advanced technology ecm motors that provide additional comfort and energy savings potential. I have been involved in the sales of these products for over 35 years.
