Common Problems With The Gas Furnace & How To Fix Them: Part 2 by Rifat
Problem 1 – Gas Furnace Blower Running Continuously
Solution: If your gas furnace running without shutting off time to time, it clearly means the gas furnace needs repair. Also, make sure the thermostat in your house is not set to the “continuous fan” setting.
Before calling the AC maintenance & repairguys, you can try to fix the problem by lowering the temperature. If it is still not fixed, the reason might be the faulty limit control switch. It will require professional HVAC technicians to reset the switch or replace it.
Problem 2 – Gas Line Is Blocked/Closed
Solution: From the main inlet to the gas furnace burner, check the entire gas line. See if the switch is switched off. Or the line may be closed by something.
If your hot water tank is not working, be sure the problem is with the gas supply in your home. Make sure the gas line is open at all times.
Problem 3 – Gas-like Smell
Solution: If you smell a gas-like odor, you might be experiencing a gas leak. If the gas-like smell is strong, leave your home immediately as your house might have filled with gas. Any type of ignition can lead to an explosion.
If it is mild, you should get the line fixed. Otherwise, it might cause severe health issues for your family members. Contact the gas line company or air conditioner servicing company. They will close the gas leak in no time.
Problem 4 – Blocked Vents
Solution: Nothing should block the intake and exhaust. If the pipes are covered with windows screen-like screen mesh, you should replace it with hardware clothes.
But if you find ice clogging in the line, be sure the problem is much worse. Clear it off and call the HVAC technicians to properly addressing this situation.
Problem 5 – Gas Furnace Not Blowing Air
Solution: If the gas furnace is not blowing the air, look into the inspection window on your furnace. Ensure the blower does not have any debris or residue. Also, pay attention to LED indication light.
If the LED is flashing green, you don’t need to worry. But if it is red, call for HVAC system experts as soon as possible. However, no light means the problem is with the thermostat, or the control board or other components of your HVAC system.
