Every fall you follow the same routine. You flip your thermostat from cool to heat and turn the temperature down to force the furnace on. You wait to hear that familiar click, for the pilot light to ignite, and for the motor to start the blower but nothing happens. Try the following first and if that doesn’t work, call Vredevoogd Heating & Cooling in Lansing.
Check Your Pilot Light
Grab a flashlight and head to your heater. Carefully remove the cover panel and find the pilot light. Do you see a blue flame or nothing at all? If you don’t see anything, your pilot light may be out. Carefully relight it per the furnace manufacturer’s instructions. If they aren’t posted on the unit and you threw away your owner’s manual, go through the following steps.
Reset the thermostat to the lowest setting. You do not want your furnace to even think about flipping on while you’re working on it. Head to your home’s breaker box and cut the power to your furnace. If you don’t know which switch it is, enlist the help of someone who can identify what each switch powers. (Label them with a marker while you’re doing this.)
Head back to your furnace and turn off its main gas supply. You should see a pipe that leads into it and there should be a knob you can use to cut the supply. Don’t turn off the furnace’s pilot light supply. It needs gas to ignite. Once you’ve confirmed the electricity and main furnace gas supply are off, carefully light a match and reignite the pilot’s flame jet.
Reset the Unit
If the pilot holds the flame, you can move forward and reset your furnace unit. If it doesn’t hold the flame, call an HVAC professional for assistance. To complete these instructions, however, we’ll assume your pilot stayed lit. Find your furnace unit’s reset button next. It should be red or yellow and labeled as such.
If you do not see it on the outside of the unit, remove the blower compartment cover. In some cases, you can simply open it; in other cases, you may need to unscrew the cover. Find the furnace reset switch near the blower — it should be on the side or back – and press it in. You may have to hold it for 30 seconds depending on your unit.
Close or screw back tight the blower cover. Replace the pilot panel and head back to your breaker box to restore electricity to your furnace. Return to your unit and restore the main gas flow. Do these steps in this order to prevent the risk of an electrical spark marrying an open gas line. Turn the thermostat on to see if your unit works.
