Coleman Evcon central air conditioner repair and replacement parts

What to do when your Coleman Evcon central air conditioner 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 central air conditioner 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.
