I am having an intermittent problem with the rear ac unit.
The unit is cooling properly, the fan works on hi &
low speed.
When the unit shuts off after reaching the correct temp, something isnt shutting down, a loud humming noise occurs in the lower unit and the only way to stop it is to shut off the breaker.
Is there a relay or something else to check thats causing this.
It happens sporadically and goes weeks without recurring.
I removed the lower anel and oened up the box with the relays on it. The compressor relay had a wire loose and now its working properly.
