Troubleshooting Fraser-Johnston Furnaces

Fraser Johnston furnaces are meant for residential use to heat the home when it's cold outside. The furnaces are built to fit into compact spaces and offer many features, including an Energy Star rating, quiet operating noise, fuel efficiency ratings of 95 and above, and they include limited warranties. If you maintain, clean, and care for the furnace on a regular basis, it operates well with few problems. If issues do arise, however, troubleshoot and fix the basic problems yourself.

Step 1

Connect the Fraser-Johnston furnace to the power supply if the furnace isn't operating. Replace or reset the circuit breaker or fuse as needed. Turn the furnace's main power switch "On" and move the control dial to "Auto" or "Heat."

Step 2

Turn the gas valve on in a counterclockwise motion to ensure there's gas supply if the furnace is running but not heating. Adjust the thermostat temperature to a setting above the current temperature, as the furnace will not run if the thermostat is set below the ambient temperature.

Step 3

Unplug and turn off the Fraser-Johnston furnace if the furnace is making a lot of noise or seems to be low on heat. Remove the front access panel door and unhook the filter from position. Clean the filter with a vacuum or wash well with cold, soapy water. Completely dry the filter before replacing it in the filter housing.

Step 4

Use a clean, damp cloth or vacuum to remove dirt and debris from the blower motor and fan if the fan is noisy. If the condensate drain is full, empty the drain pan.

Step 5

Look at the pilot light assembly and wipe clean with a damp cloth if the light isn't steady or staying lit. Dirt or grease can interfere with proper pilot light function. Adjust the metal bracket around the pilot light (the thermocouple) so that it's positioned evenly around the flame.

Step 6

Press the reset button on the control panel and close the access door firmly. Restore power. Contact Fraser-Johnston if the problem persists.
