Its a 16 year old heil gas furnace with clicking (piezo starter?)
- The thermostat turns on the furnace ok
- The furnace clicks on the ignition flame with clicking and the burners come on ok.
BUT!
- The clicking never stops, and continues randomly and rapidly even with the burners on.
- Often the burners get extinguished due to rapid clicking as the ignition (I think) for a second turns off the gas and attempts to re-start the burners again and they do come on again within 2 seconds or so.
- This whole burners going on-off and clicking stops when the thermostat turns off the furnace / target temperature has been reached.
help!
