Troubleshooting a Malfunctioning Furnace
Waking up to a cold home is not pleasant, especially if you assumed your furnace would be keeping you toasty in the Montana winter. However, try these easy troubleshooting tips to fix a malfunctioning furnace.
Check Your Furnace's Power
The first thing you should check is whether the power switch is on. Check the power switch, usually located on the furnace itself or by a box on a nearby wall that will look similar to a light switch. Sometimes, the power switch can be unintentionally bumped off during cleaning or other movement in the house. If the switch is off, turn it back on and wait a couple minutes, as there is often a delay between the switch and the furnace turning back on.
Make Sure Your Thermostat is Working
If the power switch is on, your next stop should be the thermostat. Like power switches, thermostats are susceptible to being bumped off or reset. Make sure your thermostat is set to “heat,” and that the temperature setting is accurate. The switch for the fan should also be on.
Next stop on the troubleshooting checklist is the circuit breaker box. Since both oil and gas furnaces require electricity to operate, they are connected to your home’s circuit breaker. Check if there are any popped breakers, and if so, return the popped breaker to the “on” position. In addition, your furnace may have a circuit breaker on the unit that has popped. Note – if you have reset one or both breakers once and they pop a second time, do not continue to reset them, as this could cause damage to your system. There is probably a deeper issue causing these breakers to pop, and it is time to call a professional heating service company.
Check Your Furnace Fuel Source
The easiest way to check if your gas or propane are not working is to check if other appliances that run off these fuels are working, such as a stove or hot water heater. If both your furnace and the other appliance are not working, there may be an issue with the fuel. Try checking to make sure that your gas value is in the “on” position, or if your propane tank is empty. You may just need to refill.
Blower Motor Panel
Make sure the blower motor panel is pushed in all the way; your furnace can sense if the blower motor panel is open and will not run if it is.
As part of the safety features, newer furnaces will not run if there is too much heat or pressure. This feature prevents overheating. If the air filter is dirty of clogged, the air filter can trap heat and air, setting off this function. You should replace your air filters regularly to keep your furnace running properly.
Each furnace has a condensate pan that should be draining or pumping water out to remove it. If there is standing water here, your pump or drain may have built up a blockage. You can buy tablets at your local hardware store to help clean the flow. If this is still not working, you may need a new pump.
Sometimes, troubleshooting a malfunctioning furnace can be as easy as flipping a switch or completing some light maintenance.
