Common Furnace Problems

Heating equipment is complicated, so when one component malfunctions, it impacts the entire system’s ability to operate. Here are some common reasons to contact JC Appliance Repair for emergency furnace repair:

  • The furnace won’t turn on.
  • The pilot light is out.
  • Strange noises are coming from the furnace during startup or operation.
  • The main burner won’t light or won’t stay lit for longer than three seconds.
  • The blower never turns on after the burners are lit.
  • The furnace blower stays on constantly.


Reasons the Furnace has Stopped Working Properly:

It’s easy to notice when the above problems are occurring, but they are merely symptoms of an underlying cause. Here are the top reasons your furnace has stopped working and how JC Appliance Repair technicians repair them:

No power to the furnace: If the fan doesn’t respond to raising the thermostat’s temperature, a breaker may have tripped, the wiring could be loose, or the furnace switch might be turned off. More complicated problems include trouble with the transformer, thermostat, control board, run capacitor or blower motor. A technician can perform a diagnostic test to pinpoint the exact problem and come up with a solution.

Failing motor: Squeaks and squeals may emanate from a motor that’s about to fail. Immediate attention from a technician is required to save the furnace from a complete breakdown.
No ignition: In furnaces with spark ignitions, rapid clicking sounds indicate that the burner is trying to ignite. Failure to do so could be caused by a blocked flue, faulty control board, or improper limit control. Repairing or replacing these parts should remedy the problem.

Main burner problems: Burners that won’t stay lit are most commonly caused by a dirty flame sensor or a clogged condensate drain in the case of condensing furnaces. If the burners won’t light at all, the gas supply could be cut off. Cleaning key components and making a few adjustments should be all a technician is required to do for this furnace repair.

Issues with the run capacitor or motor: These problems cause the blower not to turn on after the burners ignite.

Clogged air filter: Assuming the thermostat isn’t set to “on,” which keeps the blower motor on continuously, a clogged air filter is the primary cause of a blower motor running all the time. The restricted airflow may have damaged the limit switch, which senses the internal furnace temperature.

An JC Appliance Repair technician not only replaces the switch; he also pinpoints the problem. If a clogged filter is the cause, he will educate you on changing the air filter and the process for doing so.
