Freezer Frost or Ice Buildup? Same-Day Freezer Repair in Ottawa & Gatineau
Heavy frost or ice building up in your freezer almost always means the auto-defrost system has failed or the door is not sealing — both are common, fixable faults. B&M offers same-day freezer and refrigerator repair across Ottawa & Gatineau, TSSA-certified and factory-authorized since 1995.

Common causes of frost or ice buildup in a freezer
- Failed defrost heater. When the defrost heater quits, frost builds on the evaporator coils instead of melting away each cycle.
- Faulty defrost thermostat or timer. A bad thermostat or control stops the defrost cycle from running.
- Worn door gasket. A poor door seal lets warm, humid air in, which freezes into frost.
- Frequent or long door openings. Humid air entering repeatedly creates frost, especially in summer.
- Clogged defrost drain. A blocked drain can cause ice to form at the bottom of the freezer.
How B&M fixes it
We test the complete defrost system — heater, thermostat, and timer or control — and check the door seal, then replace the failed part and clear any ice so it stays frost-free. Defrost heaters and thermostats are stocked on the van for same-day repairs.

Frequently asked questions
Why does frost keep building up in my freezer?
The most common cause is a failed defrost heater or thermostat, so the frost that normally melts each cycle stays and accumulates. A worn door gasket is the other big cause.
Will I have to defrost it manually forever?
No — once we repair the defrost system, the freezer manages frost on its own again. Manual defrosting is only a temporary workaround.
Is it worth fixing?
Yes — a defrost heater or thermostat is far cheaper than a new freezer, and we give you the price before any work.
