Common Furnace Problems and Their Solutions

Common Furnace Problems And Their Solutions

When the winter weather arrives, many customers call furnace repair professionals because their heating system isn’t working correctly. Knowing the most common furnace problems allows you to take proactive efforts to avoid them. And you’ll know when it’s the best time to call in HVAC repair pros for issues and when you can handle them on your own.

Faulty Thermostat:

Check the thermostat. If it appears that your heater is not producing any heat, check the battery level in the thermostat.

Solution

• Sometimes replacing the battery is sufficient
• If it still does not work, turn it off and on again
• Check the thermostat that it is set to “heat”
• Check the thermostat to ensure it’s set to a greater temperature than the current room temperature

The Furnace isn’t Getting Power:

If your thermostat is working correctly and the settings are accurate, check if the furnace is switched on?

Solution

• Check whether the circuit breaker tripped if your furnace is hooked in
• If the breaker controlling the furnace is turned off, turn it back on
• If the switch is between ON and OFF, flick it to OFF before switching it to ON
• If the breaker trips again, there could be an issue with the wiring or the breaker itself

Clogged Filter:

Airflow is reduced when air filters are dirty or clogged. Typical corrosion can cause airflow issues and heat control issues.

Solution

Sweep or replace the filter monthly. A furnace repair specialist can show you how to achieve this.

Unusual Sounds:

If the furnace is unusually loud, rumbling, shrieking, and clattering, it could indicate a problem. The noises could indicate mechanical problems, decreased airflow, or a blocked burner.

Solution

Contact knowledgeable, professional furnace repair in Hillsboro to deal with these problems.

Problems with the Pilot Light or Ignition:

Natural gas is highly combustible, and if your pilot light has been turned off for an extended period, there may be a dangerous amount of gas accumulating around the device.

Solution

• Stop the gas supply and wait several minutes before relighting it
• If you have an older version with a pilot light that won’t remain lit, take professional help

Problem with the flame sensor:

When the flame sensor detects gas but no flames, it shuts down the entire system.

Solution

• Turn off your furnace’s power at the unit or by turning the circuit breaker
• Turn off the gas supply valve
• Remove the flame sensor
• Rub the sensor gently with fine-grit sandpaper or an emery board
• Replace the sensor after wiping away any leftover dust with a paper towel

Cracked Heat Exchanger:

A damaged heat exchanger can allow dangerous carbon monoxide to enter your home. It might be challenging to detect, but symptoms may include an unpleasant stench. People in your home suffer from inflamed eyes, headaches, dizziness, nausea, or flu-like symptoms.

Solution

If you suspect your furnace has a fractured heat exchanger, turn it off immediately and contact an HVAC professional like emergency furnace repair in Troutdale.
