I replaced my ADC control it ran well for a couple days and then went out again. The compressor and the condenser fan would not run. I replaced the ADC control again within a 3 day time span and it started operating again for another couple of days. I changed the harness along with ADC can anyone help?
Answer Hello Bill,
You will need to look for any component on the unit that is showing an improper resistance. Since this board basically controls the entire unit, it could be just about any component on it. You should get a test meter and the wiring diagram from the unit and start testing. There will be a component on the unit that is drawing too much current. This will show up on the ohm meter as too little resistance or a short to ground. I doubt it will be a "dead short" or complete short because that would just shoot the new board as soon as it is powered up.
I've replaced the defrost timer board and my fan still isn't coming on. What do I check next?
Answer Hello Will,
You should check for voltage at the fan motor connection. If voltage is there, the fan motor has failed.
