A refrigerator that's stopped cooling is one of the most common calls we get across Hyderabad — and in most cases, the cause falls into one of seven categories. Here's how to think through it before a technician arrives.
1. Low or Leaked Refrigerant
If your fridge feels warm throughout, not just in one section, low refrigerant gas is often the cause. This usually means a slow leak somewhere in the cooling line, and the fix is a leak check followed by refrigerator gas filling.
2. A Faulty Compressor
The compressor is the heart of the cooling system. If you hear a loud hum but no cooling, or no sound at all from the back of the unit, the compressor may have failed and could need compressor replacement.
3. Dirty or Blocked Condenser Coils
Dust buildup on the coils at the back or underneath the fridge reduces heat exchange efficiency. This is more common in Hyderabad households where coils aren't cleaned for years — a simple clean often restores some cooling.
4. A Worn Door Gasket
If the rubber seal around the door has cracked or lost its grip, cold air escapes constantly, making the compressor work harder without ever reaching the set temperature. Door gasket replacement is usually a quick, affordable fix.
5. Thermostat Malfunction
A faulty thermostat may stop signaling the compressor to run, even when the inside temperature rises. This often shows up as a fridge that cools intermittently rather than not at all.
6. Frost Build-Up on the Evaporator Coil
If the automatic defrost system fails, ice can build up around the evaporator coil and block airflow. This is especially common in older single door and double door refrigerator models.
7. PCB or Electronic Control Failure
In newer refrigerators with digital displays, a faulty PCB can disrupt the entire cooling cycle. This requires refrigerator PCB repair or board replacement by a trained technician.
What You Can Check Before Calling
- Confirm the power socket and plug are working properly
- Check the thermostat hasn't been accidentally turned down
- Make sure the door is closing fully and the gasket isn't visibly torn
- Look for visible ice buildup blocking the back panel inside the freezer
If none of these resolve it, the issue is likely mechanical or electrical — and that's where a proper diagnosis matters more than guesswork. Apex Company Refrigeration Works offers same day refrigerator repair across Hyderabad, with a clear quote before any work begins.
