The thermostat measures room temperature and tells the AC when to run and when to rest. A faulty thermostat causes two opposite problems: an AC that never stops (raises electricity bill and stresses the unit) or an AC that never starts (no cooling).
Local Thermostat Issues by City
Abha — Rapid Temperature Changes
Abha sees large temperature swings between day and night and across seasons. A thermostat calibrated for a stable temperature may give inaccurate readings during rapid weather changes. A common pattern: AC that does not stop in Abha even when the room is adequately cool.
Jazan — Humidity and Sensor Perception
Thermostats measure dry temperature. In Jazan, high humidity makes the perceived temperature higher than the measured reading. This means the thermostat may stop the AC at a reading that feels comfortable on a number but is still uncomfortable for occupants.
| Symptom | Likely Problem | Fix |
|---|---|---|
| AC never stops running | Thermostat not reading temperature | Calibrate or replace |
| AC won't start despite heat | Thermostat sending no signal | Check wiring + replace |
| Room temp doesn't match setting | Wrong calibration | Recalibrate |
| Remote unresponsive | Remote failure or reception issue | Replace remote |
