When your furnace is having problems in the middle of winter, it is an anxiety-elevating problem. Whether it’s a residential or commercial setting, a working heating system is a must. There are different issues that people encounter when it comes to furnace heating. This article will focus on some common problems and how to fix them.
No Heat
Feeling heat coming from the air ducts is one way to know if the furnace is working. If there is no heat, double check the thermostat is set to heat and that the temperature is at a comfortable level. Next check to see if the circuit breaker for the furnace was tripped, if so, reset.
Not Warm Enough
Once again, check the thermostat to see the temperature setting. Check the air filters and if they are dirty, replace them. A dirty filter will make the furnace much less efficient.
Limit Switch
The limit switch turns on the blowers that circulate the air throughout the house. There is a sensor on the limit switch to turn on once the air is warm. Otherwise the blower circulates cold air. A malfunctioning limit switch shortens the lifespan of your furnace blower. To fix it, have a technician replace the limit switch.
faulty pilot control or an electric ignition
A gas furnace heating system can either have an electronic ignition or a pilot control for a constant flame. Clogs or drafts can cause these systems to malfunction. Inspect your furnace after turning it off and follow the direction to reset the pilot or consider calling a technician.
Noisy Furnace
A rattling, rumbling and squawking furnace needs immediate attention. The noise may indicate airflow reduction, mechanical problem or a clogged burner. Several solutions may help reduce noise: insulating the ductwork and cut down the sound, adjust the pilot light or lubricate the blower motor.
Malfunctioning Thermostat
A malfunctioning thermostat in the furnace heating system may cause problems with comfort levels and air circulation. Check to ensure the thermostat is on and that the temperature displayed is accurate. If not, a technician can help.
Continuous Running Blower
A continuous running blower may be as a result of the limit switch, fixing the limit switch will fix the problem.
Safety Switches
The safety switches on the furnace heating door prevent the burner and fan from coming on after removing the access panel. If the burner or fan run when the panel is open, replace the safety switch.
Having your furnace heating system inspected periodically is another way of fixing minor problems before they become major endeavors. Furnace technician and repair professionals are qualified to provide maintenance and repair services.
