Daikin Furnace Troubleshooting
If you're looking for help fixing your Daikin Furnace, look no further! Our comprehensive Daikin Furnace Troubleshooting guide will explain common issues, provide tips, and show you how to read your model's error codes.
The electrical system that provides power to your furnace has either shorted or blown the power switch. Reset your furnace’s circuit breaker. If it is blown, you’ll have to replace it.
The furnace’s igniter is likely cracked or faulty. Check if the part has cracks and replace the igniter if it does. If it doesn’t, use a multimeter to test for continuity.
Your furnace’s thermostat may be adjusting incorrectly. If the thermostat has an adjustable calibration scale, you can adjust the heat anticipator. If this does not address the cycling or you don’t have a scale, you may have to replace the thermostat.
Not blowing hot air?
The blower motor could have burnt out. If this isn’t the case, then the connecting belt could be broken. Check to see if power is going to the motor. If it is, but nothing is working, the motor is likely dead and needs to be replaced. If the motor runs but air doesn’t move, the connecting belt has probably broken and should be replaced.
Blowing too much air?
If the relay that regulates the blower motor on the control board has stopped, it will continually send voltage to the motor. Replace the control board.
The contact that controls the blower motor on your thermostat may be stuck shut. This results in the blower motor to run constantly. Use a multimeter to check for continuity. If the problem is the thermostat, replace it.
Starting and then stopping shortly after?
Your furnace’s flame sensor checks if a flame is present. If it's defective or there's debris, it won't be able to detect a flame. If dirty, carefully clean the sensor using a fine abrasive pad. If still not working, replace the flame sensor.

The furnace and air conditioner are great. However, the thermostat is pretty complicated to make changes. I did not find useful information on the web to help me through the process of changing high and low temperature and setting the schedule.
I purchased my home in 2016 and it was built in 1977. This home is ~2,600 sq.ft. and has an unfinished basement. The HVAC system was very dated, and the furnace was likely the original. Using Legacy Heating and Air, Inc., a new full system install was done. The components used are all Daikin (aside from a water heater also replaced), and are the following: DM97MC1005CN (Furnace), DX17VSS421AA (A/C), CAPE4860C4 (Coil), DTST-CWBSA-NI-A (Thermostat). I could immediately feel the difference. There were rooms in the house that weren't getting much or any air adjustments because the old system was simply not a great fit for the house and inefficient. With the current system, I can now cool or heat the house evenly several degrees within minutes. The new thermostat is very slick, and easy to control. I haven't seen the new cost for energy consumption (not billed using new system yet), but from what I can tell is it's going to be a nice difference. Everything is incredibly quiet and I'm very pleased with this investment.
My old furnace needed replacing and I struggle with the decision to spend a little more for a modulating furnace. I finally choose a DM97MC furnace with a Daikin One thermostat. I am very impressed how quiet the system is. I can’t even hear then it runs. And, now my house is more balanced even with no swings in temperature. Very impressive.
I just recently had the new Daikin furnace installed into our home and so far I'm very impressed with both it's energy efficiency as well as it's overall quiet operation. This new unit also has a much smaller footprint than the unit it's replacing, which in turn takes up less valuable space in our utility room. I'm very pleased with making this purchase.
We purchased a new furnace and central air unit. The house seems much more cooler with so much less effort. The air condition unit outside is so quiet you can hardly hear it running. We haven’t how do use the furnace yet but I’m sure it will be just as effective. We are extremely happy with both of our set ups and Applegate cooling and heating did an amazing job installing them. The warranty coverage that comes with the system is absolutely amazing along with all the rebates.
