How to diagnose common Aaron heating and cooling combined unit problems
Here are some heating and cooling combined unit problems you might run into, and what to do about them.
- Won’t turn on. Check the house circuit breaker for the heating and cooling combined unit to make sure it’s turned on. Reset the circuit breaker if it’s tripped. Low air flow can also prevent the heating and cooling combined unit from working, so check the air filter and replace the filter if It’s clogged with lint. Check for a clogged evaporator condensate drain pipe because a drain clog can cause the heating and cooling combined unit to shut off.
- Lack of air flow through the vents. A clogged air filter can prevent air from flowing through the vents, so replace the air filter if it’s clogged. If the filter isn’t clogged, a problem with the blower fan may be causing low air flow through the vents.
- Makes lots of noise. Bearings in the blower fan can make loud squealing or screeching noise when the heating and cooling combined unit runs. Replace the blower fan if its bearings make noise while the fan runs.
Common Aaron heating and cooling combined unit parts that need replacing
- Air filter. Replace the air filter monthly or as directed in your heating and cooling combined unit’s owner’s manual. Replacing the air filter regularly helps keep the heating and cooling combined unit running smoothly and helps the unit last longer.
- Thermostat. The thermostat turns the heating and cooling combined unit on and off. The thermostat can eventually wear out or break. Replace the thermostat if it doesn’t control temperature accurately or doesn’t turn on the heating and cooling combined unit at all.
- Blower motor. The blower motor often runs for long periods without stopping. The bearings that support the motor shaft can wear out over time. Electrical problems inside the motor can also prevent the blower motor from running. Replace the blower motor if it doesn’t run or makes loud noises when running.
