Videocon AC Sensor Problem Repair in Chennai
A defective temperature/room sensor makes the AC cycle wrongly or ignore the remote.
When your Videocon split or window air conditioner starts running continuously without cooling properly, or shuts down prematurely after just a few minutes, a malfunctioning thermistor (temperature sensor) is often the root cause. Videocon ACs rely on two primary sensors on the indoor PCB unit: the ambient room sensor and the copper coil sensor. In humid coastal regions like Chennai, moisture accumulation, dust build-up, and voltage fluctuations can alter the resistance values of these thermistors. This leads to inaccurate temperature readings, causing the compressor to cycle erratically or completely ignore temperature adjustments made via your remote control.
Common Symptoms of a Videocon AC Sensor Problem- Continuous Compressor Operation: The outdoor unit keeps running non-stop, over-cooling the room and driving up electricity bills.
- Short Cycling: The AC turns on and shuts off every few minutes before reaching your set room temperature.
- Error Codes Displayed: Videocon digital displays frequently show specific sensor error codes (such as E2 or E3 depending on the model generation).
- Remote Commands Ignored: Changing the set temperature on the remote control makes no difference to the cooling intensity or fan speed.
- Indoor Unit Freezing: Frost or ice accumulates on the indoor evaporator coils due to a failing coil sensor.
- Thermistor Resistance Drift: Heat and age alter the internal resistance (kilo-ohms) of the Videocon thermistor sensor, sending false signal voltages to the main controller.
- Corrosion from Coastal Humidity: Chennai's salty air accelerates oxidation at the sensor terminal connectors where they plug into the PCB assembly.
- Pest Damage: Insects or geckos entering the indoor unit casing can chew through the thin sensor wires.
- Dislodged Coil Sensor: Physical displacement of the copper tube sensor from its designated brass pocket on the evaporator coil.
- Diagnostic Resistance Testing: Our technicians use a digital multimeter to measure the exact resistance (kOhm rating) of both ambient and tube sensors against standard Videocon technical specs.
- Wiring and Terminal Inspection: We inspect sensor wiring harnesses for breaks, shorts, or corrosion at the PCB connection joints.
- Precision Replacement: If the sensor is out of calibration range, we replace it with a compatible, high-precision thermistor rated specifically for your Videocon AC tonnage and PCB board.
- PCB Signal Calibration: We verify that the main control board receives accurate real-time feedback and properly signals the compressor relay to turn on and off.
- Final Performance Check: We monitor a full cooling cycle to ensure consistent room temperature control and proper thermostat cutoff.

Frequently asked questions
How do I know if my Videocon AC room temperature sensor is faulty?
If your Videocon AC continues running continuously without cutting off, cycles on and off every few minutes, or displays sensor error codes like E2/E3, the temperature sensor is likely out of calibration or defective.
Can I replace the Videocon AC sensor myself?
It is not recommended. The sensor connects directly to the indoor PCB, requiring multimeter testing for resistance ratings and safe electrical disconnections to avoid damaging the main circuit board.
How long does a Videocon AC sensor replacement take?
A standard Videocon AC sensor inspection and replacement usually takes about 30 to 45 minutes on-site in Chennai, provided the required sensor specification is available on the technician's service vehicle.
Does Janani Cool Care offer a warranty on sensor repairs?
Yes, all Videocon AC sensor replacements and repairs performed by Janani Cool Care come with a 30-day service warranty for your peace of mind.
