If you have your control device set to a warm temperature but you have noticed that it’s not turning on, you are likely experiencing a minor issue that you may luckily be able to repair yourself.
If your oil furnace is not turning on, you should start by checking your control unit, air filter, circuit breaker, blower cover, condensate pump plus line, plus oil furnace switches.
If your oil furnace is not turning on, the first thing you should do is check your control device plus make sure the batteries are not dead, plus the setting is on heat plus fan setting is on auto. If your control device is not on heat plus auto and/or does not have fresh batteries, it may not turn on. If everything is well, then you should next check your air filter. If your filter is clogged, it will reduce the airflow to your oil furnace, which can cause your oil furnace to overheat plus shut off! Filters should be replaced every 1-3 weeks. The circuit breaker tripping can also be a cause of the oil furnace not running regularly. If the circuit labeled oil furnace has moved to the middle or neutral position, the breaker has tripped. Turn it off plus back on. If your oil furnace was recently tested or you took the cover off of your oil furnace to check something, the blower cover may not be on as tightly as it needs to be. Many oil gas furnaces have a safety feature called a blower door safety switch that prevents the oil furnace from turning on if the blower cover is not secured tightly. If there is a block in the condensate pump or drain line, water may back up in the system, triggering the system to shut down to prevent water disfigure. If there is a blockage, a worker will have to clear it. There are a variety of safety switches in your oil furnace that each monitor a certain section of your oil furnace plus will trigger the system to shut down if that section is not working regularly. Be sure to check the pressure switch, flame sensor, limit switch, plus flame rollout switch! You might need to read your oil furnace manual to get a better idea of which switch is indicating a problem. You can also make the decision to call a Heating & Air Conditioning professional to diagnose the problem.
