Though I'd the blower out I might look up in the warmth exchanger using a flash light to view In the event the evaporator really essential cleansing. This requires that you choose to slide in to my sources the furnace blower compartment on your own again and shine a flashlight up to the furnace so you're able to see and ascertain if The underside in the evaporator is soiled or not.

Take a jumper wire and leap involving the R and W terminals over the board. This should bounce earlier the thermostat and thermostat wires. Transform the furnace energy back on. The heat must operate when the facility is utilized. If it blows the fuse once again then there is a Command board issue or even a small voltage problem within the furnace controls. In case the furnace will work then you've got a thermostat wire challenge or a shorted thermostat difficulty. Usually the thermostat wires need to be replaced if You can not visually discover the shorter. I hope that you just obtain the condition easily.

Solution: Sure, I've encountered this issue quite a few periods. This is certainly most unquestionably a brief to ground and you've got to discover what or wherever the limited is to solve the condition. Usually this problem winds up blowing the fuse around the board Should you have 1 with your furnace’s Handle board, instead of the transformer. I ordinarily suspect and have found that the thermostat wires are the situation, but other equipment with coils and electronics may also induce this problem.
