Ruud UAKA037 Air Conditioner Questions & Answers
I have a Ruud UAKA-037JAZ
Need furnace model number. It sounds like you're looking for a standing pilot. Your furnace might not have one. Very likely to have a spark ignition type system or hot surface igniter.
My Ruud silhouette II some times will not operate.
4 Blinks is an error code of a sticking pressure switch. A pressure switch is a safety, which in this case is being used to verify that your furnace is drafting properly. Yours in particular is sticking in the closed position even after the call for heat is satisfied. The control board checks to make sure the switch is open the next time there is a call for heat, and when it sees that the pressure switch is already closed even before the draft inducer motor comes on, it knows there is a problem....hence the error code. If you tap on the pressure switch, it may cause the contacts to open. Usually you will see a rubber hose attached to the pressure switch and 2 or three wires depending on what type of switch it is. You will probably have to replace the switch, but maybe this will get you thru the night. Hope this helps!
Heater will not start
If you are getting air conditioned air when you are supposed to be getting heat, the compressor is working but the valve that reverses the refrigerant flow for heat to be created could be stuck in the default postion which for a Ruud is air conditioning. There is also a special output on your thermostat to activate the heat cycle and reverse the valve.. Maybe that is not working and the cause of your anomaly.
