| My
Outdoor Unit Won't Shut Off Unless I Use The Circuit
Breaker It only happens occasionally.
Thermostat satisfied; indoor blower goes off;
outdoor unit continues to run and can only be
turned off with circuit breaker.
Only 2 or 3 things can cause this. The most common
is a stuck compressor contactor. Located in the
outside unit, the contacts get pitted and eventually
weld shut. This can cause serious damage. Some
authorities think it is good practice to replace
the contactor every few years just like you would
replace the spark plugs in an automobile.
Other causes would be a shorted thermostat cable
or a defective thermostat.
Below is a list of possible causes and usually
require a service technician to correct.
- Stuck contactor
- Defective thermostat
- Thermostat cable shorted
Hope this has been of some assistance, however
they are just rough guidelines and not all possible
conditions are covered.
