After a power outage, your furnace may not turn on right away. This is because the power outage can cause a reset in the furnace’s electronic control board. The best way to reset the board is to turn off the furnace at the breaker box and then wait for 30 seconds before turning it back on.
If your furnace still doesn’t turn on, you may need to replace the control board.
If you have a furnace that isn’t turning on after a power outage, there are a few things you can check before calling a professional.
First, check your thermostat to make sure it’s turned on. If it is, then check to see if the switch on your furnace is in the “On” position. If it’s not, turn it to the “On” position and wait a few minutes to see if the furnace turns on.
If it doesn’t, check to see if there’s a tripped circuit breaker or a blown fuse. If so, reset the breaker or replace the fuse.
If that doesn’t work, call a heating contractor to have your furnace professionally inspected.
The thermostat Won’t Turn on After Power Outage
If your thermostat won’t turn on after a power outage, it may be because the power was out for too long and the thermostat needs to be reset.
To do this, simply turn the thermostat off and then back on again. If the problem persists, check to make sure that the thermostat is getting power.
If it is, then the problem may be with the thermostat itself and you may need to replace it.

Furnace Reset Button
If your furnace is acting up, one thing you can try is resetting the furnace. This is a simple process that involves pressing the reset button on your furnace. This can sometimes fix issues like a dirty filter or incorrect settings.
If your furnace won’t turn on, make sure to check if the reset button has been tripped. The reset button is usually located near the bottom of the unit. Once you find it, simply press and hold it for a few seconds until you hear a click.
If this doesn’t work, you may need to replace your furnace altogether.
Gas Hot Water Heater Not Working After Power Outage
If you have a gas hot water heater, it may not work after a power outage. This is because the pilot light needs to be lit in order for the unit to function. If you find yourself in this situation, there are a few things you can do.
First, check to see if the pilot light is lit. If it is not, then you will need to relight it. This can be done by following the instructions on your unit.
Once the pilot light is lit, you should be able to turn on your hot water heater and have it work as normal. If the pilot light is lit but your hot water heater still isn’t working, then there may be an issue with the gas supply.
Check to see if the gas valve is turned on and if there is no blockage in the line.
You may also want to contact your gas company to see if they can help troubleshoot the problem.
What Would Cause a Furnace Not to Kick On?
There are a few different reasons why your furnace might not kick on. The first thing you should check is whether or not there is power running to the furnace. If the furnace isn’t receiving any power, it won’t be able to turn on.
Another possibility is that the thermostat isn’t set correctly. The furnace won’t turn on if the thermostat isn’t set to a temperature that’s high enough to trigger the heating cycle. If those two things are both fine, then it’s possible that there’s an issue with the furnace itself.
It could be a problem with the igniter, for example, or with one of the other components inside the unit. If this is the case, you’ll need to call a professional for help diagnosing and repairing the issue.
FAQs
Can a Power Outage Damage a Furnace?
Yes, a power outage can damage a furnace. If the power is out for an extended period of time, the furnace may overheat and cause a fire. Additionally, if the power is restored suddenly, it could cause a surge that could damage the furnace.
Will Furnace Come Back After Power Outage?
If you have a furnace with an electronic igniter, it probably won’t come back on after a power outage. Even if your furnace has a pilot light, the gas may have shut off during the outage. If this is the case, you’ll need to relight the pilot light before your furnace will work again.
Where is the Reset Button on a Furnace?
If your furnace has a reset button, it will be located on the control panel. This is typically found on the side or front of the furnace. The exact location will vary depending on the model and make of your furnace.
If you cannot find the reset button, consult your furnace’s owner’s manual for more information.
Conclusion
After a power outage, your furnace may not turn on right away. This is because the furnace needs to reset itself after the power has been restored. If your furnace doesn’t turn on within a few minutes of the power being restored, you should check to see if the circuit breaker has been tripped.
If it has, simply reset it and try again. If your furnace still doesn’t turn on, you may need to call a professional for help.
