When your furnace stops working in the middle of a cold, winter night, what should you do?

If you live in Philadelphia, Delaware or Bucks County, you call AJM, that’s what! We go above and beyond to make sure you’re comfortable, for the right price. Before we start any maintenance or repair work, we thoroughly explain whatever issue is at hand as well as your options, so you can make an educated decision on how you’d like to proceed.

How do I know if something is wrong with my furnace? Look for the following signs:

  • The pilot light is out
  • The main burner won’t light or stay lit
  • The blower won’t turn on after the burners are lit
  • The furnace blower remains on constantly
  • It’s making strange sounds

If you encounter any of these circumstances, call us, and we will determine the underlying cause of the symptom. Here are common reasons why your furnace has stopped working:

Power Failure

If the fan doesn’t respond when you raise the thermostat, the wiring could be loose, a breaker might have tripped, or the furnace switch might be turned off. However, it might be something more complicated like trouble with the thermostat, control board, transformer, run capacitor or blower motor. One of our technicians can perform a diagnostic test to identify the exact problem and resolve it.

Motor Failure

If you hear hissing or squeaking and squeals from your motor, then it’s probably about to fail. Immediate maintenance from one of our technicians can save your furnace from breaking down completely.

No Ignition

Furnaces with spark ignitions make rapid clicking sounds when the burner is attempting to ignite. Failure to ignite might be due to a blocked flue, faulty control board or improper limit control. Replacing or repairing these parts can resolve this issue.

Main Burner Problems

Burners that don’t stay lit are usually caused by dirty flame sensors or clogged condensate drains. If the burners don’t light at all, the gas supply might be cut off. Some minor cleaning along with making a few adjustments should do the trick.

Run Capacitor or Motor Issues

If the blower doesn’t turn on after the burners ignite, then your run capacitor or motor requires attention.

Clogged Air Filter

If the blower motor is running all the time, your air filter is the probably clogged. The restricted airflow might have damaged the limit switch, which senses the internal furnace temperature. Our technician can replace the switch and teach you how to change your air filter.
