Losing your heat in the middle of winter can put your life in danger. Watch this video to learn how to stay warm when your furnace stops working.
Here are the four problems that happen most often with furnaces. Read on to find out how to fix many of these problems and what you can do to keep them from happening again.
One of the most common furnace problems is that there is no heat. There’s no one thing that could have caused the lack of heat, so you’ll have to look into it to find out what’s wrong.
First, make sure the thermostat is working. You can turn off the heat or set it to a low level. If this is the problem, change the setting on the thermostat.
If the problem isn’t the thermostat, make sure the propane valve is closed. If a valve is closed, propane can’t get into the furnace to heat the air. If it’s locked, you can open it yourself or ask a professional for help if you need to.
A blown fuse is the third thing that could cause there to be no heat. This fuse needs to be changed out. You will need to set up a gas furnace repair to do this.
When working with propane, you should always be very careful. Teach your kids about safety with activities that are fun and easy for the whole family to understand.
Lastly, if your furnace has a pilot light, look through the tiny window on the front of the furnace to see if it is on. The tip of the flame should touch the thermocouple. If your furnace doesn’t have a pilot light but instead uses an electronic ignition, check to see if it is on.
Fan is Not Running
If you find that the fan on your furnace is not running, look first through the inspection window in the blower compartment.
Do you see a green light that blinks? If so, move on to the next tip on how to fix a broken furnace.
If your furnace has a red light or no light at all, the transformer, control board, blower motor, or run capacitor could be broken.
Check the breaker if you saw a green light. If it trips, look at the control board to see if there are any loose wires or burned spots. Do not turn on the power again until these problems have been fixed by a trained professional.
Blower Does Not Turn Off
You suddenly realize that your gas furnace’s blower has been going nonstop for at least an hour. What’s next?
Do some troubleshooting to find out if the problem is the setting or the fan.
First, look at the thermostat to see if the fan is set to run all the time. The fan shouldn’t be on all the time because it needs to cool down between uses. You should set your thermostat to automatic so that the blower can turn on and off as needed.
The fan’s control switch could also be the reason why the blower won’t turn off. If the switch doesn’t let the blower turn off, you will need to replace this part.
