Power outages affect a large home’s Heating & A/C system, especially gas furnaces.
Ordinarily, it stops the normal functioning of a modern gas furnace.
However, your heating program should power back when the indoor lights come back on. Sometimes, this does not happen, causing confusion among local homeowners. At this point, you have to get your hands dirty & problem check your gas furnace or get the services of a qualified Heating & A/C repairman. If you ever decide to problemshoot the gas furnace on your own, you need to start first by looking for a tripped breaker. Often, a power surge from an erratic power supply trips up your home’s main circuit breakers to protect your apartment from the excessive power supply, and locate your home’s electric control panel & carefully look for breakers with red color at their switch window, however push the central breaker to the ‘off’ position & turn it back on. The switch window will turn rapidly from red to green, & your gas furnace will begin to work. Your control unit may also eventually need resetting after a power outage. However, it may go to service mode & therefore will have to be reprogrammed before your gas furnace resumes normal operations. This whole phenomenon is normal with smart control units. This problem could cause your gas furnace to cycle continuously without heating up. You definitely have to call a qualified Heating & A/C contractor to service the problem. But I recommend you take a look at things yourself first, just to save some of your spare cash.
