A control component controls your heating and A/C system’s functions by determining the amount of heat produced by the furnace.
It can get stuck in the on or off position and affect your heating and A/C unit’s normal function.
When it does, you will need to service it by first determining the causes for the sticking. A build-up of grease, debris, and dirt can cause your control component to get stuck. When your control component gets stuck in the closed position, your heating and A/C method will overheat since there will not be any coolant circulation. To service this, you should first turn the power to the HVAC method off. The next step is to detach the cover by following your manufacturer’s directions. Brush and vacuum the control component carefully to detach dust and dirt from the contact point and lever switches. Wipe the more than one metal strips with a soft cloth and use a crisp dollar bill to detach dirt from the crevices. Then slip a 7/32″ wrench onto the hex nut below the bimetal while you hold the temperature adjustment lever in a stationary position. Turn the hex nut clockwise until you open the switch. Then adjust the lever to the lowest temperature setting; Replace the cover and wait for the temperature to stabilize before moving the temperature adjustment lever to correspond to the room temperature, mount the control component in a locale where the air is consistent with the room temperature. Regularly cleaning your house control component will help clear grime, dirt, and dust. It ensures your HVAC method runs well without any hiccups! Consult your heating and A/C professional to calibrate the control component if you cannot do it on your own. If the control component continues to fail despite regular cleaning and service, you should get a upgradement from your local heating and A/C contractor or get in touch with your heating and A/C repairman.
