Furnace Repair – How to Do It Yourself

Furnace Repair

If you notice that your furnace isn’t functioning at all, it may be time for some Furnace Repair. Repairing this problem is a great way to improve its efficiency and safety. Follow the steps below to fix your furnace. Once you have them sorted out, you’ll be well on your way to a more comfortable home. Fortunately, there are several things that you can do yourself to prevent the need for a repairman.

Check if the power switch is in the “ON” position

If your furnace isn’t turning on, you may need to check if the power switch is in the “On” position. Many people mistakenly turn off their furnace power switch for a light switch. If you notice that the furnace isn’t working, you may need to replace the fuse or reset the breaker. If the furnace is still not working, check to see if there are other issues with it, such as a draft inducer motor or a pressure switch.

Check the circuit breaker

If your furnace is not blowing warm air, the breakerĀ Furnace Repair may be tripped for several reasons, including an overheating motor or airflow restriction. A dirty air filter, for example, may cause the circuit breaker to trip, causing the blower motor to work harder than it needs to. Dirty air filters may also cause the circuit breaker to trip due to suffocation, requiring the furnace blower to run harder. Rather than trying to fix this issue on your own, it is best to hire an HVAC professional.

Check the air filter

To do this job properly, you should first locate the air filter. The air filter is usually located near the blower system on the front of the furnace, near the bottom. It may be accessible without opening the furnace, or you can pull the metal panel off with screws or hooks. Slide the clean air filter into the slot, making sure that it is pointing away from the return drop. Once the air filter is removed, check the air filter to make sure it is in good condition.

Check the limit switch

Before performing any furnace repair, it’s important to determine whether the failure of the limit switch is due to a wiring problem or a physical defect. The two most common ways to diagnose a failed limit switch are with a multimeter and by looking for obvious signs of malfunction. If the switch is bad, the next step is to replace it. You can do this yourself by unplugging the furnace, finding the switch on the access panel, and using a multimeter to test the switch’s resistance. The switch itself is usually easily identifiable, but sometimes it needs to be replaced, so make sure to get a replacement that is an exact duplicate.

Check the thermostat

To troubleshoot a malfunctioning thermostat, you must first identify what’s wrong with it. Some thermostats are wired to the house’s electrical system, while others use batteries and flash a low-battery symbol when they need to be replaced. If your furnace uses a battery-operated thermostat, first check the battery by opening the device and cleaning it of debris. Check the date and time on your thermostat as well as the furnace fuse.
