I have a RUUD UAMB-036JAZ. It doesnt run anyore. Also the thermostat went blank. Carrier thermostat CFTCHCCPUISA2-GEN ( The breakers are on. I switched them on and off couple of times) I dont know if the AC stopped working first or it is a thermostat iissue. It is my understanding that if AC line voltage disappears completely, the display will turn blank.
SOURCE: AC breaker trips after 10 minutes
Whats the amp breaker? Is this for the inside unit or the outside condenser? If the inside and gas heat you have a bad fan motor, If its an electric furnace , the same, but if its the outside unit, the fan could be going bad, locking up and the compressor still runs and pulls high ampsand tripps breaker or the compressor is just pulling too many amps due to plugged coils with dirt , grass or weeds blocking airflow.([email protected])

Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...

SOURCE: ruud heater will not light consistently
Your furnace is going into a lockout condition, cycling the power resets the circuit board and it starts over. I will need to know approximate age and model of your furnace, it sounds like you have need to clean the flame sensor rod. However i need to know what i am working with.
SOURCE: The outside fan motor (OFM) will not turn off.
You probley have both power wires hooked to the bottem or power side of the contactor switch, one should be pluged into the bottem of the contactor, and one to the top, so when the switch opens, it breaks contact between the two wires (turns motor off).
