  1. Hot surface ignitor constantly glows after furnace is running 5min after furnace is running rollout switch trips shutting down the furnace.. I cleaned flame sensor rod,meter reads 1.1 as furnace is running. Hot surface ignitor never shuts off which gets to hot by rollout tripping it. Ignitor ohms out at 140. If u can help me with this problem I would very much appreciate it. Thanks an have a good day..

    1. Hi Darryl! Sorry to hear that you are having trouble with your furnace ignitor not going off and over-heating the roll-out switch. I would suggest trying a new ignitor first. 140 ohms is a little high and is a sign that the ignitor could be on its way out. Most of the time when this problem occurs with the ignitor not shutting off, it is caused by a stuck ignitor relay on the control board. You probably need a new control board. I would suggest unplugging the ignitor then test with a volt meter where you unplugged the ignitor. The meter should be set to “Volts AC”. See if the control board is still sending 110 to 125 volts to the ignitor. If it is then you have a stuck relay on the control board and the board will need to be replaced to solve the problem. If you would like for me to look up and try to see which control board your furnace uses then please send me your furnace’s model number and serial number to our email address: arnoldservice@gmail.com. I hope you can easily find and fix the problem. Steve
