As residents make the switch from air conditioning to heat in Deerfield, Illinois, some might find their heaters won’t start. When a home heater won’t kick on, it’s a frustrating concern that’s best remedied by calling in a professional HVAC company. Here are a few common reasons your heater won’t start.
Lack of Power
When there’s a tripped breaker or blown fuse in the main electrical panel, the furnace can’t ignite. Check the power supply to make sure the breaker is on. If in doubt, turn it off before turning it back on.
Does your home use a gas, oil, or propane furnace? If it won’t turn on, it might be because of a closed gas valve. You may also be out of fuel.
Open the valve. Check the fuel source, and order more as needed.
Wrong Thermostat Settings
In some cases, your heater might not kick on because your thermostat is set wrong. Make sure the unit is switched over to heat and turned to the on position. Raise the temperature about five degrees to see if that helps.
Ignitor in Lockout Mode
Furnaces that have hot surface ignitors can switch to lockout mode, which is indicated by a blinking light. You will need to reset the power switch by turning it off and on.
If the heater still does not ignite after doing so, there may be damage to the ignitor itself. The only solution to this problem is having the ignitor replaced by a service technician.
When a heater motor overheats, it needs to cool down before it can provide the proper heating your home needs. Try turning the heater off altogether for at least half an hour before pressing the reset button. Sometimes it will kick on after the first try. But you may need to repeat this process more than once before the motor has enough time to cool.
