Heater Repair or Lack of Power?

Oftentimes, when we get a call that a heater is broken, we find that the customer simply didn’t realize their furnace wasn’t getting power or gas. This simple fix is often overlooked, so be sure to check that your heater has power and gas before you do anything else. To check this, first reset your heater by turning it off for a few minutes and then back on. If it’s still not working, check your breaker to make sure it’s not the source of the problem. To see if your furnace is getting gas, check if you’re able to get hot water or use your stove if it’s gas driven. Also, if you have a furnace that uses a pilot light, make sure the pilot light is lit.

Check that filter!

The most common problem with broken heaters is a clogged filter. If your furnace becomes too clogged, most furnaces will revert to a safety mode that blows only cold air to avoid serious damage. Air is filtered before it reaches the furnace itself, so look for furnace slot, which is usually at the meeting of the return duct (where the cold air comes in) and the main body of the furnace. Once you remove the old dirty filter, insert the new one, make sure it’s facing the right way, and that’s it! Easy right?

Replace the Thermostat Batteries

The thermostat is another source of avoidable calls to your HVAC technician. If the thermostat isn’t doing anything when you operate it, there’s a good chance the batteries are dead and simply need to be replaced. Another possibility is that the wiring needs to be replaced. Check to make sure the wires are securely connected, especially if you have an old thermostat.

Make Sure Your Heater Door is on Tight

Most furnaces have a safety switch, which will shut off your heater if the cover comes off. If your heater door is loose at all, the switch may activate and prevent your heater from working.

Replace the Igniter or Heat Sensor

If you don’t have a pilot light driven furnace, your igniter may be causing your furnace problems. If your furnace is providing no heat, check the igniter. Check your owner’s manual to locate the igniter. If the igniting element appears very white, you’ll know it’s time to replace it. Replacing the igniter is fairly simple to do, and while each furnace is different, it’s usually a matter of shutting off your furnace, unplugging the old igniter, and plugging in the new one.

If your furnace provides some, but not enough heat, you should check the heat or flame sensor. If it appears to be corroded, simply purchase and install a new one. Check your furnace manual or search online to find the specific location of the heat sensor in your furnace.

 

Remember that sometimes, heaters require an experienced technician’s repair skills. If you’ve tried all of the above fixes and still don’t know what’s wrong, call your local HVAC technician.
