Answer to continue safely
Is it safe to keep using?
Maybe. The unit is functional if it reaches near the set temperature, but continuous compressor operation risks premature failure. Address the root cause promptly.
Can I reset the code?
Yes. Unplug for 5 minutes and restore power to reset the control board and thermostat. Set to mid-range and allow 2 hours to stabilize.
When to stop immediately?
Stop if you notice: Compressor makes grinding or clicking sounds while running, Cabinet temperature never drops below 55 °F despite running.
Symptoms You May Notice
Constant low hum at all times
A continuous motor hum can be heard from beneath the unit at all hours, with no pause for an off cycle.
Cabinet never reaches set temperature
The interior stays a few degrees above the set point while the compressor runs non-stop attempting to compensate.
Unit sides and rear feel very warm
The exterior panels of the unit are noticeably hotter than normal to the touch from continuous heat rejection through the condenser.
Energy use noticeably higher
Electricity consumption increases because the compressor is running 24 hours a day instead of its normal duty cycle.
Possible Causes
High ambient temperature
In installations above 95 °F ambient, the temperature differential between the cabinet and the outside air is too small for the compressor to efficiently reach set point, so it runs continuously.
DIY PossibleBlocked condenser airflow
Debris, surrounding cabinetry without adequate clearance, or vegetation near the unit prevents the condenser from rejecting heat, forcing continuous compressor operation.
DIY PossibleLeaking door seal
Constant warm-air infiltration through a failed gasket keeps the cabinet temperature above the set point, never allowing the compressor to satisfy the thermostat.
DIY PossibleFailing thermostat or temperature sensor
A faulty thermostat continues calling for cooling even when the cabinet has reached temperature, running the compressor unnecessarily.
Requires ProfessionalSafe Checks You Can Do
-
1
Check ambient temperature and add shading
Measure the air temperature around the unit. If above 95 °F, adding shade can dramatically reduce compressor run time. Direct sun on the unit body adds significant heat load even when ambient air is cooler.
A pergola or shade sail over an outdoor kitchen can lower the unit's surface temperature by 20 °F or more.
-
2
Clear ventilation clearances
Ensure at least 1 inch on both sides and 2 inches at the rear are free of obstructions. Remove any objects, rugs, or vegetation touching the unit.
The condenser fan on most DCS outdoor units draws air from the front bottom grille — keep this area clear of leaves and debris.
-
3
Test the door seal
Perform the dollar-bill test around the entire door perimeter. Replace the gasket if any section releases the bill without resistance.
Gasket replacement kits for DCS RF15 models are available through Fisher and Paykel authorized parts suppliers.
When to Call a Professional
Contact a qualified technician if:
- Compressor runs constantly even overnight when ambient temperatures drop below 75 °F
- All clearances are correct and gasket seals well but problem persists
- Temperature sensor reading is erratic in service mode
