Installing a natural gas heater is the perfect way to keep your home warm and cozy on those cold nights, but when something goes wrong it is important to know what steps to take. Learning how to diagnose, troubleshoot and repair your natural gas heater can save you both time and money, helping you get the warmth you need without the cost of a professional repair person.

Check the Thermostat

When your natural gas heater stops working, the first thing to look at is the thermostat. Carefully check to make sure the thermostat is set to heat, and make sure that the set point of the thermostat is above the ambient room temperature. It is important not to guess at the temperature in the room--take the time to bring a thermometer into the room to get an accurate reading. You can check the operation of the thermostat by changing the set point to a couple of degrees above the temperature in the room. If the heater does not come on, the thermostat may be faulty.

Check the Fan

If your natural gas heater is not throwing off any heat, it is important to listen carefully to hear if the fan is running. If the fan is not running, be sure to check the fuse to make sure it has not blown. Also check the circuit breaker to make sure it has not been tripped. If you find that the circuit breaker has been tripped, check the heater for loose connections and replace any worn wires before turning the breaker back on and trying to light the unit.

Check the Pump

Many natural gas heaters come equipped with a condensate pump that stops the unit from running if the reservoir is full. If this condensate pump is not working properly, the reservoir will fill up quickly, preventing the natural gas heater from running properly. If you suspect that the condensate pump may be bad, empty the reservoir and run the heater. If the reservoir continues to fill up, the pump will need to be replaced.
