Air Conditioner Troubleshooting

What To Do If Your System Does Not Work 
Before Requesting a Service Call: 
1. Check thermostat settings. Make sure to select a temperature below the actual room temperature. Make sure the system selector switch is in the COOL position. 
2. Inspect your return air filter. Replace a dirty filter or clean a reusable type filter. 
3. Check circuit breakers and/or fuses. Reset breakers or replace fuses as necessary. 
4. Inspect the coils and fins on the outdoor unit. Clean away any obstructions (grass clippings, leaves, dirt, dust, or lint). Check that branches, twigs, or other debris are not obstructing the fan blade. 

Regular Maintenance Requirements 
Your system should be regularly inspected by a qualified service technician. Many dealers offer this service at a reduced rate with a service contract. Some service contracts offer additional benefits such as parts discounts and no additional charge for “after hours” or emergency service. Between visits, there are some routine maintenance procedures you can do to help keep your system operating at peak performance. 

Operation under Extreme Conditions 
Your air conditioner will run as long as necessary to maintain the indoor temperature selected on your Wall Control or thermostat. On extremely hot days, your air conditioner will run for longer periods at a time than on moderate days. Your system will also run for longer periods of time under the following conditions: 
• Frequent opening of exterior doors 
• Operating laundry appliances 
• Taking hot showers 
• More than the usual number of people present in the home 
• More than the normal number of electric lights in use 
• Drapes or blinds are open on the sunny side of the home 

Do Not Operate Below 55°F (13°C) 
Your outdoor unit is not designed to operate when outdoor temperatures are lower than 55°F (13°C) without modification. If operation below this temperature is required, consult your authorized dealer. 

Do Not Block Floor, Wall or Ceiling Vents 
When drapes, furniture, toys or other common household items block vents, the restricted airflow lessens the system’s efficiency and life span. 

Sea Coast Coil Maintenance 
Coastal locations require additional maintenance of the outdoor unit due to highly corrosive airborne ocean salt. Although your new system is made of galvanized metal and is protected by top-grade paint, we suggest washing all exposed surfaces and the outdoor coil about every 3 months. Consult your dealer for cleaning intervals and procedures or ask about a service contract for scheduled professional cleanings.

Furnace Troubleshooting

Not heating?  
Your furnace’s electrical system has potentially shorted, or the power switch has blown. Reset the furnace-associated circuit breaker. If it has blown, you will have to replace it. 
The furnace’s igniter might either be cracked or defective. Check the part for cracks, replace the igniter if it’s cracked.. If it isn’t, test with a multimeter for continuity. 

Cycling irregularly?  
Your unit’s thermostat might be adjusting incorrectly. Should the thermostat have an adjustable calibration scale, use this to adjust the heat anticipator. If this doesn’t work or you don’t have a scale, replace the thermostat. 

Not blowing hot air?  
The blower motor might be burnt out. If this doesn’t seem to be the case, then the connecting belt may have snapped. First, see if power is reaching the motor. If it is but isn’t running, the motor has failed. If the motor runs but air doesn’t move, the connecting belt has probably broken. Replace the belt. 

Blowing too much air?  
If the relay that regulates the blower motor on the control board has failed, it will continually send voltage to the motor. Replace the control board. 
The contact that controls the blower motor on your thermostat may be sticking. Use a multimeter to check for continuity. If it appears the thermostat is the issue, replace it. 

Starting and then stopping shortly after? 
Your furnace’s flame sensor detects if a flame is present. If it is either defective or dirty, it will not be able to detect a flame. If dirty, use a fine abrasive pad to clean the sensor. If faulty, replace the flame sensor.
