Thermostat Not Reaching the Set Temperature
One of the most reported thermostat issues is when the room temperature doesn’t match the setting.
- Dust and dirt buildup: Over time, sensors may get blocked, giving inaccurate readings. Cleaning inside the thermostat with a soft brush often helps.
- Wrong placement: If your thermostat is placed near windows, direct sunlight, or vents, it can cause false readings. Relocating it may solve the issue
Thermostat Not Responding to Changes
If your thermostat won’t let you adjust the temperature, it may be due to:
- Low batteries or no power supply.
- Wiring problems, such as loose or corroded connections.
- Locked controls, often activated by mistake.
If quick fixes don’t help, professional service is the safest solution.

AC or Heating Runs Non-Stop
In UAE summers, the last thing you want is an AC that won’t stop running. This thermostat issue usually points to:
- Fan settings: If it’s set to auto, the fan may run continuously. Adjust to on to fix it.
- Faulty thermostat: If the system ignores commands, it may be time for a replacement.
Blank Thermostat Screen
A blank screen can be worrying, but it often has simple causes:
- Dead batteries replace them and check if the display returns.
- Tripped breaker for wired models, check your electrical box.
- Safety switch issues sometimes linked to moisture or overheating.

Thermostat Not Turning On
This issue can be caused by:
- Wrong mode settings (set to “cool” or “heat”).
- Overheated system, often due to clogged filters or blocked vents.
- Broken thermostat, which may need a replacement.
