Godrej AC Thermostat Issues Repair in Chennai
A faulty thermostat misreads temperature, so the AC over- or under-cools.
When your Godrej split or window air conditioner starts erratic cooling cycles—running continuously without cutting off, or shutting down before the room reaches your desired comfort level—the issue almost always traces back to a malfunctioning thermostat or thermistor assembly. Godrej units relying on precise resistance readings from their indoor NTC (Negative Temperature Coefficient) sensors often struggle in Chennai's high humidity, where corrosion or thermal paste degradation leads to inaccurate temperature reporting to the main PCB.
Common Symptoms of Thermostat Failure in Godrej ACs- Short Cycling: The compressor repeatedly turns on and off every few minutes, failing to maintain steady cooling.
- Continuous Operation: The outdoor unit refuses to trip, turning your room uncomfortably cold and causing high electricity bills.
- Inaccurate Temperature Displays: The set temperature on the LED panel does not match the actual room feel, or the unit displays error codes like E2/E3 indicating room sensor faults.
- Evaporator Ice Formation: Frozen coils caused by the compressor continuing to run even when liquid refrigerant temperatures drop too low.
- Faulty NTC Room Sensor: Loss of proper resistance values in the Godrej temperature sensor due to age or electrical surges.
- PCB Signal Failure: Microcontroller on the main circuit board failing to process signal inputs from the thermostat array.
- Loose Wiring Connections: Oxidized terminals or loose socket connections between the sensor wiring harness and the indoor PCB.
- Incorrect Sensor Placement: The room ambient sensor slipping out of its factory clip on the front evaporator coil assembly.
- Diagnostic Resistance Test: Our Chennai technicians measure the precise ohm resistance of your Godrej sensor using a digital multimeter against factory calibration charts.
- Sensor Realignment or Replacement: If damaged, we replace the faulty thermistor with an original, brand-compatible Godrej sensor component.
- PCB Relay Inspection: We verify that the compressor relay on the indoor board opens and closes cleanly based on temperature signals.
- System Recalibration & Testing: We run the unit through full cooling cycles across varying set points to ensure reliable compressor cut-off and cut-in.

Frequently asked questions
Why is my Godrej AC running continuously without tripping?
A faulty ambient room sensor or damaged relay on the PCB often prevents the Godrej AC from detecting that the target room temperature has been reached, forcing the compressor to run indefinitely.
How long does it take to replace a Godrej AC temperature sensor?
Testing and replacing a damaged room sensor or coil thermistor on a Godrej AC typically takes about 30 to 45 minutes on-site.
Can a bad thermostat cause the indoor evaporator coil to freeze in a Godrej AC?
Yes, if the thermostat fails to cut off the compressor when temperatures get too low, moisture on the evaporator coils will freeze, restricting airflow completely.
Do you provide a warranty on Godrej AC thermostat repairs?
Yes, Janani Cool Care provides a standard 30-day service warranty on all labor and sensor replacement work performed on your Godrej AC.
