Lucy Soboleva Key Takeaways
- A compressor running above design temperature degrades insulation and can cause an electrical fire.
- F&P ActiveSmart refrigerators use variable-speed compressors; sustained overheating triggers protective shutdown and food spoilage.
- Condenser coils clogged with dust force the compressor to run longer cycles, raising operating temperature significantly.
- At least 50 mm of clearance at the rear and top of the refrigerator is required for adequate heat dissipation.
The Bottom Line
Keep condenser coils clean, maintain manufacturer clearances, and replace door seals when they lose their grip — these three steps prevent the majority of compressor overheating events.

The compressor is the heart of every Fisher & Paykel ActiveSmart refrigerator — a sealed, motor-driven pump that circulates refrigerant continuously to maintain safe food storage temperatures. When a compressor overheats, the consequences range from premature failure and costly food spoilage to, in extreme cases, an electrical fire originating in the motor windings or wiring harness. CPSC data consistently identifies refrigerators as a leading source of home appliance fires, and restricted heat dissipation is a primary contributing factor.Emergency Response
| Symptom | Immediate Action |
|---|---|
| Burning smell from behind or beneath the refrigerator | Unplug immediately — do not use the outlet again until an electrician inspects the wiring |
| Compressor extremely hot to touch (rear lower panel) | Pull the refrigerator away from the wall to restore airflow; if smell persists, unplug and call a technician |
| Refrigerator contents warming despite the appliance running | Check door seals and condenser area; if unclear, move perishables to alternative cold storage and arrange a service call |
| Repeated clicking without the compressor starting | This indicates thermal overload protection activating — unplug for 30 minutes to allow cooling, then call a technician if the fault recurs |
What Causes Compressor Overheating
ActiveSmart refrigerators dissipate compressor heat through condenser coils, typically located at the rear or beneath the cabinet. When those coils are coated in dust and pet hair, thermal resistance rises and the compressor must run longer to achieve the same cooling effect, driving up its operating temperature. Poor installation clearance — pushing the unit flush against a wall or enclosing it in cabinetry without ventilation gaps — compounds the problem. A failing door seal allows warm ambient air to enter continuously, forcing the compressor into extended run cycles. In older units, degraded compressor motor insulation can cause intermittent shorts that generate localised heat well before a fault code appears.Warning Signs
- The rear panel or floor beneath the compressor compartment is noticeably warm to the touch
- The compressor runs almost continuously rather than cycling on and off
- Interior temperatures are higher than the set point despite normal door use
- A faint burning or hot-plastic smell, particularly noticeable when standing near the rear of the unit
- Increased electricity bills without a change in household habits
- Visible frost build-up inside the cabinet, indicating the evaporator fan or defrost system is compromised
Prevention DO/DON'T
| DO | DON'T |
|---|---|
| Vacuum condenser coils and the compressor area once a year using a brush attachment | Don't push the refrigerator flush against the wall — maintain at least 50 mm rear clearance |
| Check door seals annually by closing the door on a sheet of paper; if it slides out easily, replace the seal | Don't place the refrigerator beside a heat source such as an oven, dishwasher, or direct sunlight |
| Ensure top and side clearances meet the specification in your F&P installation guide | Don't ignore a compressor that runs continuously for more than 30 minutes — investigate promptly |
| Keep the interior temperature set between 3°C and 5°C to avoid unnecessarily frequent cycles | Don't block the interior vents with oversized food containers |
