Burners ignite intermittently
Posted: Tue Mar 16, 2010 2:41 am
I have a Coleman 7966-656. Please advise as to what might cause the burners to ignite intermittently. Typically, I will have to do a complete shutdown and wait for an hour or so to get the furnace to work. Once it fires up, it will cycle anywhere from 1 to 5 or 6 times and then the burners will not ignite again and it will "lock out". Occasionally, I can get it going again by re-setting the thermostat several times but usually, I have to shut it down again and wait. Thanks in advance for your help/
