Here is the situation.
The house and outbuildings are all hooked up to an oil well that provides gas. We had a severe cold snap over the last few days and that resulted in a gas interruption from the oil well. We fixed that issue and the gas pressure has resume to the house. We were all able to get the downstairs main furnace to restart on its own. However we have been unable to get the upstairs furnace to work or the outbuildings furnace to work. Both the outbuilding and the upstairs have a York brand furnace. The outbuildings furnace is a furnace/air conditioner combined unit located outside of the building and sharing common ducting. Since it is hard to access the internals of that unit, I assume it is self-lighting and I'm not been able to get any further as far as resetting it. All I know is that the gas is restored and the furnace is not working. The outbuilding furnace/air conditioner combination unit was installed around 2007/2008. The upstairs furnace is a little different. It appears to not respond to the commands from the thermostat(analog controls). However there is a button on the furnace itself that when pressed blinks once, indicating "lockout-check furnace". If I continue to hold this button press down the furnace will go through it start up cycle, will kick on ,will light the burners, and will turn on the fan. As soon as I remove my finger from the button the furnace will stop everything instantly. It might appear that it wasn't talking or wasn't connected to the analog thermostat. However if while holding down the button on the furnace and getting the burners to light and continue to burn, somebody switches the button on the analog thermostat from heat to off, the furnace will turn off everything instantly. I'm guessing both furnaces are having an issue related to the short-term low pressure situation. I have already tried turning off the power to the upstairs furnace for a period of time of up to three or four minutes and trying to see if it would work afterwards. There has been no change. Does anyone have any suggestions on how to reset the furnaces or maybe something else is wrong? Considering they are working fine before this low-pressure situation, I'm guessing they just need to be reset. The one in the house I can confirm indicates lockout. |
