How do I know if my thermostat is malfunctioning?
7 Signs You Need to Replace Your Thermostat
- Your HVAC Keeps Turning On or Off.
- Faulty Thermostat Readings.
- Suspiciously High Energy Bills.
- Constant Temperature Shifts.
- Thermostat Is Too Old.
- Thermostat Fails to Respond to Changed Settings.
- Your HVAC System Short Cycles.
Why would a thermostat stop working?
If the thermostat runs from the house’s electrical system, check on the circuit breakers. One of them might have tripped and cut off the power the thermostat. Reset the breaker. If this doesn’t work, then the issue with the thermostat could come from loose connections or other wiring problems.
Why is my thermostat not regulating temperature?
Sometimes, a cooling and heating system won’t hit the thermostat temperature because the calibration is not correct. This is most commonly a problem if you have a newer thermostat or have recently lost power due to a power outage or low batteries. An old thermostat may also need recalibration over time.
How do you fix a malfunctioning thermostat?
How to troubleshoot your thermostat—and possibly fix it in minutes
- Check the power circuit. Are the thermostat and the AC/furnace receiving power?
- Try replacing the batteries on the thermostat. This simple step alone resolves many thermostat issues.
- Clean it. Some thermostats open easily so you can clean the inside.

What does the boiler temp control knob do?
This control knob adjusts the temperature of the water coming from the boiler. This water is used by the heating system controls for two different purposes. Firstly, it is sent directly to the radiators when the central heating is ON, so this is the temperature to which the radiators will heat.
Do you have a bad thermostatic temperature control?
If you have a refrigerator that never cycles on or a refrigerator that runs continuously, freezing everything in the refrigerator and freezer compartments, the chances are good that you have a bad thermostatic temperature control.
What happens if the boiler temp is set too low?
If the boiler temperature control is set too low, the hot water cylinder thermostat will never be satisfied and will continuously ‘call for heat’ (as we say in the trade) so the boiler will continuously cycle ON and OFF. This wastes fuel and heat so paradoxically, for economy it is better to set the boiler temperature control higher than lower.
Why is the temperature control on my Refrigerator not working?
If the temperature control passed the electrical function test but the refrigerator runs continuously, freezing everything in the refrigerator compartment, the problem is a defective temperature sensing bulb on the temperature control.
