Videocon AC Thermostat Issues Repair in Chennai
A faulty thermostat misreads temperature, so the AC over- or under-cools.
When a Videocon air conditioner fails to maintain a comfortable room temperature, the issue often stems from a malfunctioning thermostat sensor or an impaired electronic control board. Videocon split and window units rely on precise resistance readings from NTC (Negative Temperature Coefficient) thermistors to signal the compressor on or off. A drifted or faulty sensor leads to wild room temperature fluctuations, keeping your space either uncomfortably warm or turning it into an icebox.
Common Symptoms of Videocon AC Thermostat Failure- Continuous Compressor Running: The compressor fails to cut off even after the room becomes uncomfortably cold, freezing the evaporator coil.
- Premature Short-Cycling: The Videocon unit turns on and off rapidly every few minutes without adequately cooling the room.
- Temperature Misreadings: The digital display shows inaccurate room temperatures or triggers error codes related to sensor communication.
- No Cooling Output: The blower fan operates normally, but the thermostat fails to send a voltage signal to engage the outdoor compressor unit.
- Out-of-Calibration Thermistor: The resistance values of the room temperature sensor alter over time due to wear, humidity, or thermal stress, feeding incorrect data to the microcontroller.
- Loose PCB Connector: Physical vibration can loosen the sensor harness plug connected to the mainVideocon indoor PCB motherboard.
- Dust and Debris Coating: Accumulation of dirt on the sensor bulb insulates it from actual room airflow, causing delayed response times.
- Relay Defect on Control Board: A stuck or damaged thermostat relay on the PCB keeps the compressor permanently energized or completely isolated.
- Sensor Diagnostic & Resistance Test: Our technicians use digital multimeters to test the resistance (kΩ) of the Videocon sensor against standard factory temperature curves.
- Sensor Replacement: If out of spec, we replace the faulty thermistor with an accurate, high-grade sensor compatible with Videocon control circuits.
- PCB Circuit Inspection: We verify the signal path on the indoor PCB, replacing faulty onboard relays or repair damaged traces if required.
- Re-calibration and Testing: After installation, we measure ambient temperature differential, running amp draw, and automatic cut-in/cut-out thresholds to ensure accurate operation.

Frequently asked questions
Why is my Videocon AC running continuously without cutting off?
This usually happens when the room temperature thermistor has failed or lost calibration, causing it to constantly read a higher temperature than reality and keeping the compressor powered.
How long does it take to replace a Videocon AC thermostat sensor?
A standard thermistor replacement and circuit testing typically takes about 30 to 45 minutes at your home in Chennai.
Is it safe to bypass the Videocon AC thermostat sensor temporarily?
No, bypassing the sensor forces the compressor to run continuously, which can quickly freeze the indoor evaporator coil and cause major damage to the compressor.
Do you provide a warranty on Videocon AC thermostat repairs?
Yes, Janani Cool Care provides a standard 30-day service warranty on all Videocon AC repairs and replaced components.
