- 1). Check to see if a fuse has blown and if the main power is on if the heater isn’t working at all. Ensure that the gas supply is turned on at the meter.
- 2). Check the thermostat to ensure it’s set at the correct temperature and the control switch to ensure it’s working if you aren’t getting enough heat. Call a technician to have either replaced if they are broken.
- 3). Open up the main gas valve to the heater and purge air from the gas line if the heater will start but doesn’t ignite. Turn the unit on and off a few times to get air out of the line.
- 4). Set the gas pressure to the proper setting according to your specific model, and check to ensure the gas valve is set to “On” if you aren’t getting ignition.
- 5). Remove any obstructions from in front of the vents, and reconnect the motor hose if it has come off if the warm air isn’t being distributed properly.
- 6). Check for any loose connections around the air circulation fan if it isn’t working properly. Switch off the fan time-delay relay switch if your unit has one.
