Yesterday I called White Heating, Inc. because my furnace was acting up. I was at home standing by the tech the entire time he had his hands in the furnace. The Tech that came to look at my furnace diagnosed the problem with the blinking indicator light. The light was telling him “Ignition failure (check ground)”. The Tech check the ground to the furnace and ground to the board. He did not check ground to the igniter or the flame rod that was sending the signal back to the board. He automatically jumped to the conclusion that is was a bad board. He gave me a price of $280 for the new board plus another $98 to install the part, on top of the $98 for ½ hour I paid for the service call. I called the same supply house that White uses since we have an account and got the part for almost $100 cheaper and replaced myself. I have been a service tech for over 10 years on car washes, so replacing a plug and play board was not an issue. Low and behold this was not the issue! Since the Tech did not check any other parts I am now out $182.81 for the board. The dirty flame rod that sent a signal to the board was the issue, it needed cleaned. This was a $10 part I picked up this morning to have a spare. Just to make sure that the board was not the issue I placed my old board back in and it works just fine. The sad thing is that if the board was the issue there is a 5 year manufacture warranty on it since it was installed in June 2011. John at White called back this morning stating he was going to refund me the money for the service charge but could not do anything for me on the board. I give them credit on trying to make the situation right.
