Official Kenmore heating & cooling combined unit parts

Common Kenmore 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.

What to do when your Kenmore heating and cooling combined unit isn't cooling

• Check the thermostat settings. Make sure the thermostat is set to the Cool setting. Check the temperature setting and adjust it if necessary. If the thermostat isn't working, shut off the house circuit breakers for the heating and cooling combined unit and check the thermostat wiring connections. Replace the thermostat if wiring connections are okay but the thermostat won't power up.
• Check the house circuit breakers for the outside unit. Reset the house circuit breakers for the outside unit. Check the breaker on the side of the house near the outside unit and reset that breaker if it's tripped.
• Change the air filter. A clogged air filter can cause the evaporator to freeze up. Replace the air filter if it's dirty.
• Check the condensate drain line. A clogged condensate drain line will cause water to back up in the condensate drain system and trip the drain overflow float switch. The air conditioner won't cool when that drain float switch trips. Clear the clogged condensate drain line to reset the float switch.
• Clear debris from around the outside unit. Leaves and grass around the outside condenser unit can prevent the air conditioner from cooling properly. Clear any grass, leaves or other debris from the outside of the condenser unit.
