WeatherKing gas furnaces are meant primarily for residential use for placement in utility closets, attics or other small spaces. The company's upflow gas furnaces are 34 inches in height, which allow the units to fit in compact areas and offer a patented heat exchanger that resists corrosion. WeatherKing gas furnaces offer a direct spark ignition, preventing the need to manually light the pilot light, and a slow-open gas valve for quiet operation. Standard maintenance and care will help the furnace operate well for years. However, if problems do happen, troubleshooting efforts may help identify the issue and offer a resolution.

Step 1

Look to make sure the furnace is properly connected to a power supply and gas supply if the furnace is not operating. Reset any household circuit breakers or fuses if necessary. Ensure the furnace is turned "On" and the thermostat is set at a temperature above the ambient temperature, as the furnace will not turn on if the room temperature is warmer than the thermostat temperature setting.

Step 2

Turn off the "Continuous Fan" setting on the thermostat if the furnace fan is running continuously. Select the "Auto" mode to allow the furnace to run the fan as needed.

Step 3

Turn off the furnace and unplug from the power source if the furnace is running loudly. Remove the front panel door and use a clean, damp cloth to clean the gas burners. Dry with a clean, soft cloth and then stop and smell for gas. If you smell gas, stop immediately and leave the house. Call your local gas company or fire station. If no gas is detected, follow the directions in step 5 to relight the pilot light.

Step 4

Find the thermocouple tube, which is located at the base of the control box and is the smaller of the tubes, if the pilot light is not staying lit. Follow it up inside the water heater to the top and then tighten the nut next to the tip. Stop and smell for gas. Leave the house and call your gas company if gas is detected. If no gas is detected, follow the directions in step 5 to relight the pilot light.

Step 5

Ensure the gas control knob is turned "Off" and turn the temperature control dial to the lowest possible setting. Wait five minutes for gas to clear from the system. Turn the gas control knob to "Pilot" and push it down. Press the ignition button and continue to hold down the gas control knob for 30 seconds after the pilot light is ignited. Release the gas control knob and move it to "On".

Step 6

Contact an authorized service technician if problems remain.
