Suppose you’ve been having issues with the temperature in your home. However, you’re not sure if the heating and cooling system is to blame, but your thermostat could be a problem. Check for these typical thermostat issues before calling for air conditioning services in Allentown, PA.
The AC Suddenly Stops Working
Check to see if the thermostat’s display is turned on. If it isn’t, the thermostat won’t be able to tell the air conditioner to turn on. Look for and fix minor causes of no power to the thermostat, such as dead batteries, a tripped breaker, or a blown fuse in the main electrical service panel.
What to Do:
- If you’re sure it’s getting power, turn off the thermostat breaker to securely remove the cover and inspect the insides.
- Check for dirt, soot, cigarette smoke, or dust buildup first. The regular operation can be harmed by a buildup of junk on the mechanical and electrical components, so clean them carefully using canned pressurized air or a soft brush.
- Check for apparent faults with the components, such as loose wiring or terminal screws that need to be tightened after cleaning.
- If the wire appears to be eroded, you can either replace the thermostat or utilize the wiring schematic in your owner’s manual as a replacement guide.
Room Temperature Never Reaches the Thermostat Setting
A buildup of dirt can cause inconsistencies between the temperature setting and the actual room temperature. A faulty installation or a significant impact might throw a usually level thermostat off. Temperature differences may result as a result of this.
If this is the case, adjust the thermostat by placing a carpenter’s level above or below it until it sits level. If the thermostat is mechanical, another reason can be a stuck heat anticipator. Find the anticipator by looking for a small metal arm sitting on a circular dial with the cover removed. If you gently push the arm in any way, it should become free.
What to Do:
- If the thermostat is inconvenient, it will not regulate the temperature effectively; therefore, examine its placement in your home.
- Relocating it may be beneficial if it is in direct sunshine, near a heat source, or exposed to cold draughts.
Frequent Short Cycling or Continuous Running
Short cycling and practically constant operation, which erodes energy efficiency, can be triggered by a thermostat that doesn’t sit level or is dusty inside.
What to Do:
- To lengthen the cooling cycle, move the anticipator arm in single-notch increments toward the round dial indicator indicating longer.
- Allow the AC to run for a complete cycle between changes until you see a difference. If the problem is not solved after the above troubleshooting steps, have an expert HVAC specialist investigate further to determine the root cause.
