The last thing you want your heater to do is not to work when you need it the most. Heating problems are fairly common in households and buildings alike, but it’s not that difficult to diagnose provided you know the process.
Lone Star Comfortaire, your HVAC repair experts, shares a step-by-step guide to diagnosing a heater that won’t turn on.
Check the Thermostat
First, check if the thermostat has power and make sure it’s set to the heating function. The temperature setpoint must also be higher than the ambient temperature in the room. Set the fan on the thermostat to “on” just to be sure.
Check the Power
Next, you will have to check the power. What most homeowners don’t realize is that even gas-powered heaters use electricity and your heating problem may, in fact, be an electrical problem. Check the circuit breaker and make sure that the heating equipment isn’t tripped.
You’ll then want to inspect the systems power cords for signs of damage and replace the ones that have any tears or cuts. Finally, check the heating system’s control board for burn marks as these are clear signs that the system may have sustained an electrical short.
Inspect the Condensate Pan
The condensate pan is a forgettable part of the heating system and is often the source of your “no heat” problems. If its full, then the heater won’t turn on. You simply need to drain the reservoir to fix this. Make sure to check the condensate pipes for blockages so that the pan doesn’t fill and stay full.
