Question about Ruud UBHC Air Conditioner
I have ruud 90 plus achiever furnace about 11 years 0ld. the other day I noticed that the my house was getting cold and the furnace wasn't coming on. When I tried to reset it as per the instructions it didn't work until I turned the power and gas off and tuned back on 6 hours later in the morning that it worked. It worked for 18 hours and now same problem same solution again. How can I fix this problem?
Look in the small peep hole on the cover when the furnace will not come on look in and try to count the number of slow and fast flashes and you will have a code ON THE panel somewhere there will be a key with all the possible codes this will help you determine whats wrong.
Sounds like a pressure switch or high limit

Sounds like the unit goes in lockout mode which shutting off the power and putting it back on will reset the computer now the next time it happens dont shut off the power and in the blower compartment on the board there will be a blinking light count how many times and on the door it will explain do not remove the door until you have counted the beeps throgh the little hole

Look on the condensor, (outdoor unit) at the very bottom of the rear panel and you should find a red reset button. push it. If that does not solve the problem, and the outdoor unit is running (make sure both the fan AND the compressor are running) then you are looking at a low refridgerant issue and possibly dirty coils.
In that case, clean the coils and have refridgerant added.
