How to Troubleshoot Your Furnace – Loveland Colorado

The experience of switching on your furnace and discovering that it produces no heat is an unpalatable one. Many things may be responsible for this occurrence. Highlighted below are some troubleshooting tips that will enable you to know the actual problem with your furnace. Following these tips will enable you know if you can fix the problems on your own.

Ensure The Furnace Is Set To “Heat”

Lots of people do not set their thermostats right. Thus, the first troubleshooting step that you need to take is to ensure that he thermostat is set to “Heat.” Many thermostats are physically set to “Heat,” as a result, the switch can easily be moved while dusting. Also, make sure that the set point is at the actual temperature that will switch on the furnace.

If after giving the furnace about a minute for the fan and the heat to come on, you notice no difference, adjust the thermostat to 900F. This should prevent it from turning on and off when you’re troubleshooting.

Check The Filter

Problems related to filters are one of the commonest problems associated with furnace problems. This is because most homeowners do not pay attention to filters. Filters help to clean the air coming into the furnace as well as the heated air going into the house. Dirty and clogged filters inhibit the flow of air thereby leading to the buildup of heat and pressure on the furnace.

The newer and more efficient models of furnaces are more sensitive to this problem and will usually shut down before it leads to more damage. Other units will continue running with less output and reduced efficiency. To know if your furnace has a filter problem, check the filter for dirt. It is recommended to replace filters once every month.

You can also know if your furnace has filter problem by listening for a whistle. If enough air can’t pass through the furnace, it will pull air through any available opening thereby leading to a whistling sound.

Is The Furnace Getting Electricity?

Check to see if the furnace gets electricity. Majority of the furnace thermostats have switch for the fan that reads “On” or “Auto”. Turn the switch to “On.” If the fan works, then the furnace is getting electricity. If not, then you have other problems.

Check The Circuit Breaker

If after all the previous tips there is no improvement in the way your furnace works, then you need to go to your home’s breaker panel and find the circuit that controls the furnace. The purpose of checking it is to see if it is in the “Off” position or in the middle. Throw the switch to “Off” and then “On.”

Follow The Light

Pilot light can also help pinpoint the issues with your furnace (although furnaces that are less than 20 years old won’t have this feature). If you have a furnace with a pilot light, follow the instructions in the owner’s manual to relight the pilot.

Check The Gas Valve

If every other thing fails, check the gas valve of your furnace to ensure that it has not been switched to “Off.”
