Check The Thermostat
This is the 1st place to search for a problem. It’s quite feasible that you don’t have furnace trouble at all. The furnace won’t operate unless it receives the signal from the thermostat.
Ensure your thermostat wiring isn’t broken anywhere down the line to the furnace. If you happen to discover any breaks, an easy splice that’s wrapped with electrical tape will supply a temporary fix.
Open the thermostat cover and look for loose wiring. Your thermostat ought to be sitting level and securely attached. Remove any dust.
Make Sure The Furnace Is Turned On
You don’t need a furnace repair call if all that’s needed is the flipping associated with a switch. Make sure the power switch to the furnace is ‘on’. It looks like any typical wall switch and you’ll find it located either on the furnace or on a nearby wall.
Be sure the circuit breaker line or even the fuse as well as the furnace is delivering power.
Look at the panel that sits over the blower motor. The furnace can’t operate if it is not securely closed. When it’s in the right position, it depresses a switch that allows it to work.
Change The Furnace Filters
The main cause of furnace operating failure is clogged filters that cause overheating and premature shut-off. You’ll know this is the problem if the blower motor is running but there is no heat coming through.
Look at the furnace manual to locate the filter, learn how to remove it and the best replacement size/type.
Please understand that a clogged, soot-laden filter results in a dirty heat exchanger as well. Efficiency is greatly reduced and of course the furnace can sustain life-shortening damage. Replace cheap filters monthly during your heating season. Inspect pleated filters every month or two and change them as needed.
Is The Gas Turned On?
Don’t overlook this step just because it seems too simple. It’s possible that someone deliberately turned the gas valve into the ‘off’ position last spring and then forgot to turn it back on.
In case your gas line has a levered handle, make sure it’s positioned parallel to the pipe. When it’s perpendicular, it’s turned ‘off’.
An older furnace probably has a pilot light. Remove the panel on the front of the furnace and then visually check to see of the pilot is lit.
Flush The Drain Lines
Furnaces that are highly efficient drain gallons of water every day. Ensure there is no mold or dirt build-up that’s shutting your furnace down.
Cleaning the drain hose is easy. Simply remove the hose, fill it with water that has 25% bleach and let it sit for several minutes. Flush it outside and put it back into place.
Check For Restricted Air Flow
Once your furnace is running some rooms may remain cold, be sure that all air registers are fully open.
Look at the ductwork for gaps or breaks. Seal them with a special duct tape that’s made from metal.
When you’re there be on the lookout for any levers that might be jutting out a little distance from duct work. These dampers should be in the ‘open’ position.
Check For Blocked Intake Or Exhaust Vents
That is applicable when your gas furnace is vented on the side of your house. Make sure the vents are completely clear of any debris.
Similarly, if there’s a heat pump, check for debris build-up near the outside compressor fins.
