What can I check if my air conditioner is not working?
. Check to see if the outdoor unit is running.
A. If the unit is not running, turn the thermostat to the
off position. Go to your circuit panel and turn the
breaker for the air conditioner off, then back on.
Go to the thermostat and turn the system back to cool.
If the system does not come on, you need a service
call. B. If the unit is running, check to see if you have the
thermostat turned to the desired temperature.
Check to make sure the air filter and the outdoor coil
is free of debris. If all of these are clean, then you will
probably need a service call. What can I check if my heat is not working?
Verify if the blower fan in the furnace is running.
A. If the fan is not running, turn the thermostat fan to the
'on' position. If the fan turns on you will require a service
call. This can indicate a problem with the thermostat
or fan center. B. If the fan does not turn on, check if the blower
door on the furnace is properly closed. Door must be
tightly sealed in order to make contact with the blower
switch.
If the door is not ajar, you will find a safety switch (toggle
switch) on the side of the furnace. Turn the switch off,
then back on. If the fan comes on, the heat should work.
If the fan does not come on then you will require a service call.
