If your fridge in Biharsharif or anywhere across Nalanda district has suddenly stopped keeping things cold, or the cooling has just gotten noticeably weaker over the past few weeks, there's a clear, ranked list of causes worth checking before you assume the worst. Most fridge cooling issues are fixable for far less than people expect.

The 6 Most Common Causes, Ranked

1. Low Refrigerant Gas (Slow Leak)
Most common cause we see

A slow gas leak is the single most frequent reason a fridge gradually cools less and less over weeks or months rather than failing all at once. You might notice the fridge section staying lukewarm while the freezer still partially works, or both sections gradually warming.

Fix: A technician runs a leak test to find the exact location before refilling — refilling without finding the leak means the same problem returns in weeks. Gas refill costs ₹800-₹1,400 in Biharsharif depending on refrigerant type and fridge capacity.

2. Dirty Condenser Coils
Free to check, simple to fix

The condenser coils, usually at the back or bottom of the fridge, release heat as part of the cooling cycle. When covered in dust and grime, they can't release heat efficiently, forcing the compressor to work harder for less cooling result.

Fix: A simple cleaning with a brush or vacuum, often free as part of a service visit, or done yourself in 10 minutes if you can access the coils safely.

3. Door Seal (Gasket) Worn or Damaged
₹300-₹600 for gasket replacement

If the rubber seal around the door has cracked, warped, or come loose anywhere along its length, cold air escapes continuously and warm air enters, making the compressor run far longer than it should just to maintain temperature.

What to check: Close the door on a piece of paper at multiple points around the seal and try to pull it out. If it slides out easily anywhere, that section of the seal isn't gripping properly.

Fix: Gasket replacement, ₹300-₹600 depending on fridge model and door size.

4. Faulty Thermostat
₹350-₹600

The thermostat senses internal temperature and tells the compressor when to run. If it's misreading temperature or has a worn-out contact point, the compressor may run too little to actually cool the fridge properly, even though you can hear it running occasionally.

Fix: Thermostat replacement and recalibration, typically ₹350-₹600 including labor.

5. Evaporator Fan Not Circulating Air
₹500-₹900

In frost-free models, a small fan circulates cold air from the evaporator coil through the fridge and freezer compartments. If this fan fails, the freezer might stay reasonably cold while the fridge section above or below it warms up significantly, since cold air isn't being pushed through.

What to check: Is the freezer cold but the fridge section warm? That combination points strongly to a fan issue rather than a gas or compressor problem.

Fix: Evaporator fan motor replacement, ₹500-₹900 including labor.

6. Compressor Fault
Least common, most expensive

If the compressor itself has failed, you'll typically notice complete silence where you used to hear periodic humming, combined with no cooling at all rather than gradually weaker cooling. This is the least common cause among the six, but understandably the one people worry about most.

Fix: Compressor replacement runs ₹2,500-₹4,500 depending on fridge capacity and compressor type. Always get a second diagnosis before approving compressor replacement, since several of the cheaper causes above can sometimes mimic compressor symptoms.

Cooling Weak vs. No Cooling at All — Why the Distinction Matters

💡 Use This to Narrow Down the Cause Fast

Gradually weaker cooling over days or weeks usually points to gas leak, dirty coils, or a door seal issue — the compressor is still working, just less effectively. Sudden complete loss of cooling with silence from the unit points more toward a compressor or major electrical fault. Mentioning which pattern you're seeing helps a technician arrive with the right diagnosis already half-formed.

⚠️ Don't Keep the Door Open Repeatedly to "Check" Cooling

Opening the fridge frequently to see if it's getting colder actually makes the underlying problem worse temporarily, since each opening lets warm air in. If you suspect a cooling issue, keep the door closed as much as possible and call a technician rather than checking every hour.
