Your furnace may be blowing cold air and not shutting off due to issues with the thermostat, a malfunctioning heating element, or a problem with the blower motor. It is recommended to contact a professional HVAC technician to diagnose and fix the issue.
There could be several reasons why an electric furnace won't shut off, including a malfunctioning thermostat, a stuck relay, or a problem with the limit switch. It's best to have a professional technician inspect and diagnose the issue to ensure safe and proper operation of the furnace.
It sound like the thermostat is broken
If your furnace won't shut off, it could be due to a malfunctioning thermostat that is stuck in the "on" position or misreading the temperature. Another possibility is a dirty air filter that restricts airflow, causing the furnace to overheat and continue running. Additionally, issues with the limit switch or a faulty relay could be preventing the system from turning off. It's advisable to check these components or contact a professional for a thorough inspection.
it wont snow in January because we have had cold wind blowing from Norway and warm air blowing from the Atlantic ocean witch put the 2 together and it makes mild wind
This problems could be the injectors. However it may also be the coil if the coli is going bad it will does this constantly.
did you try blowing it
Thermocouple is probably bad and needs replacing.
Blowing black smoke is indicative of an oil leak in the engine.
It starts cold
Try drying off the spark plug and spark plug wire area with a hair dryer. The engine may be flooded now so remove the spark plug and let the spark plug and cylinder dry out also.
occasionally wen they wont shut up
If you have a water heater in the unit there may be a shut off before that, usually at the floor or follow the cold side to a shut off. There may be an access panel behind the shower, possible in a hall closet but not always and there might be shut off valves there, but not likely. If your water heater is in the basement, there should be a shut off for each unit there.
