Emergency Freezer Repair
A freezer failure puts your food at risk. Keep the door closed to maintain temperature as long as possible—a full freezer can stay cold for 48 hours if unopened. Call us immediately for priority scheduling to minimize food loss.
Freezer Not Maintaining Temperature?
If your freezer isn't cold enough, check these items before calling for service:
- Temperature setting — Ensure it hasn't been accidentally adjusted
- Door seal — Close the door on a dollar bill; if it slides out easily, the seal needs attention
- Condenser coils — Dirty coils reduce cooling efficiency (clean every 6-12 months)
- Air circulation — Don't overpack; air needs to circulate around items
- Clearance — Ensure adequate space around the unit for heat dissipation
Defrost System Repairs
Frost-free freezers use a defrost system to prevent ice buildup. When this system fails, you'll notice:
- Thick frost on freezer walls
- Reduced cooling capacity
- Freezer runs constantly
- Water leaks during defrost cycle
We repair and replace defrost heaters, defrost timers, defrost thermostats, and control boards to restore proper operation.
