Question about Ruud UBHC Air Conditioner
When I turn the ac or the heater on it wont stop running and the heat pump outside dose not shut off either. I have replaced the thermostat and shut it off for about too weeks bur it still funs constantly running and if I have it on cool the coils freeze up in the unit and its starting to bug the heck out of me and I want to get it fixed so it dose not cost me in the long run can you help
Sounds like tstat is wired wrong or possibly the contactor relay has fused shut outside. if you can stop the system from running at the tsat it is usually a problem with the t-stat
if you cannot shut off the outside unit without turning off the power at a breaker than usually the contact relay needs replacement
