Common WeatherKing Furnace Problems and How to Diagnose

Them

When your WeatherKing furnace acts up, the ﬁrst step is to pinpoint the problem. Many

issues stem from simple causes that homeowners can address without needing a

technician. However, recognizing when professional help is necessary is equally

important.

Furnace Not Turning On

One of the most frustrating problems is when the furnace refuses to start. Here are some

common reasons and how to check them:

Thermostat Settings: Ensure the thermostat is set to “heat” and the temperature

is higher than the current room temperature.

Power Supply: Check if the furnace’s circuit breaker has tripped or if the power

switch near the unit is turned oﬀ.

Ignition Problems: WeatherKing furnaces typically use electronic ignition systems.

A faulty ignitor or pilot light can prevent the furnace from ﬁring up.

Blown Fuse or Tripped Safety Switch: Inspect the furnace fuse and reset any

safety switches that may have been triggered.

If all these basics check out, but the furnace still won’t start, it may be time to call a

professional for a deeper diagnosis.

Furnace Blowing Cold Air

Sometimes the furnace runs, but only cold air comes out of the vents. This can be due to:

Dirty Air Filters: A clogged ﬁlter restricts airﬂow, causing the furnace to overheat

and shut oﬀ the burner, resulting in cold air blowing.

Thermostat Malfunction: If the thermostat isn’t signaling the furnace correctly, it

might run the blower without heating.

Fuel Supply Issues: For gas furnaces, ensure the gas valve is open and that gas

supply is uninterrupted.

Ignition or Flame Sensor Problems: If the ignitor fails or the ﬂame sensor is

dirty, the burner won’t stay lit.

Regular maintenance, including changing ﬁlters and cleaning components, can prevent

many of these issues.
