Furnace Troubleshooting
We will tell you how to fix problems that can pop up at any time of an hour. However, if unable to detect the real problem, don’t hesitate to call the heating repair in Lawrenceville, GA.
This guide is for the HVAC systems that use natural gas or propane as their energy fuel.
Furnace Troubleshooting 1 – The Thermostat
If your HVAC system is not working perfectly, then check the thermostat. The first step is to check whether the thermostat is working or not.
A thermostat is a part of the HVAC unit, and it helps in adjusting the temperature of the heating system.
Firstly, make sure that the thermostat is on heat mode. Its temperature should be above or less than ideal room temperature. If not, then try to make the changes.
Adjust the settings to ON mode if the furnace fan is not running.
Furnace Troubleshooting 2 – The Power
If your furnace is not starting, then follow the tips given below.
First of all, check the fuse or the switch of the furnace. If there is a tripped-down fuse, then check for the loose connections in the wiring. Moreover, check for burnt spots on the board. If you find one, call the technicians to replace it.
Secondly, make sure that the light in the inspection window of the blower container if the HVAC system is glowing green. If not, the problem lies with the blower motor, capacitor, control board, or thermostat.
Thirdly, check whether the condensate pump reservoir is not filled up to the brim. A float switch automatically shuts down the furnace if the reservoir is full. If it is, then check the unit’s power and change the furnace pump. After the blower motor runs, the fan could be inserted again in the automatic mode at the thermostat.
Furnace Troubleshooting 3 – The Pilot Light
If there is a standing pilot light, make sure it is lit and touches the top of the thermocouple. If not, replace the thermostat.
If the light is glowing, but the main burners are not working, and the furnace side is not warm, the problem lies with the limit control, control board, or thermostat.
After these steps, check whether the main burner works or not. Then, check for the furnace blower. The final step is to check the heating cycle of the furnace. After 2-3 minutes of the heating system shut down, the fan should stop running. If it doesn’t, it needs replacement! For any help or guidance, Contact us at Diego HVAC!
