AC Thermostat Not Working in Sharjah
When the AC ignores the temperature you set, the thermostat or its sensor is usually the culprit - sometimes a simple fix.
Quick answer
If your AC thermostat or remote isn't working, start with the basics: fresh batteries and the correct mode. If the unit still won't respond to temperature changes, it's likely a faulty temperature sensor, a wall-thermostat fault, or a control-board issue. A technician tests the sensor and controls to restore accurate temperature control.

What problem are you having?
Pick the symptom and we'll bring the right parts and tools.
Thermostat, sensor or board?
Many 'thermostat' problems are just a dead remote or the wrong mode. Rule those out first.
If the AC runs but ignores the set temperature - never switching off, or not cooling to target - the temperature sensor or control board is usually reading wrong. That needs testing and replacement.

SharjahFrequently asked questions
Why won't my AC respond to the thermostat?
After ruling out batteries and mode, it's usually a faulty temperature sensor or control board reading the wrong temperature. We test and replace the faulty part.
My AC never switches off - is that the thermostat?
Often yes - a sensor reading too warm makes it run non-stop. We check the sensor and calibration.
Can you replace a faulty AC sensor or board?
Yes, sensor and control-board faults are routine repairs; we quote the part before fitting.
