Question about Ruud UBHC Air Conditioner
My ruud Silhouette ii (UGPH-07EAUER) furnace comes on and heats the house for about 10 minutes. Then it shuts down normally and immediately restarts - no pause at all. This repeats for 2 or three times in the morning (when the house is cold) and then the furnace works normally (on a while off a while) for the rest of the day. Acts like some kind of temp limiter in the heat box shuts the furnace down and as soon as the burner goes out cools enough to let the thermostat restart the furnace???

There is a limit switch that is likely opening. Be sure your filters are clean and all registers and grilles are open and not obstructed. If the problem continues, you may have a dirty indoor coil or undersized duct work. Some models have a window where you can observe the LED lights. If when the furnace shuts down you see any blinking, you need to count the flashes and we can figure out what the problem is from there.
