Fisher & Paykel Refrigerators 1 Error: Power supply fault
Fisher & Paykel refrigerator error code 1 is a mid-severity fault meaning Power supply voltage fault detected. If the voltage issue is confirmed to be in the household circuit and not the refrigerator, you can use the appliance on a known-good outlet while arranging an electrician visit.

Answer to continue safely
Is it safe to keep using?
Maybe. If the voltage issue is confirmed to be in the household circuit and not the refrigerator, you can use the appliance on a known-good outlet while arranging an electrician visit. If the power cord is damaged, stop use immediately until the cord is replaced.
Can I reset the code?
Yes. Code 1 will clear on its own once supply voltage is restored to the normal range. Power-cycling resets the fault log. If it returns immediately, measure the supply voltage and check the outlet circuit.
When to stop immediately?
Stop if you notice: Power cord is visibly damaged or the plug shows burn marks, Circuit breaker for the refrigerator circuit trips repeatedly.
Symptoms You May Notice
Code 1 displayed
The display shows the number 1, which may flash or appear alongside a temperature reading.
Refrigerator resets unexpectedly
The appliance powers off and restarts on its own, indicating the main board has detected an out-of-range supply voltage.
Display dims or flickers
Fluctuating incoming voltage causes the display backlight to flicker or the display to blank temporarily.
Possible Causes
Low or high household voltage
Mains voltage outside the rated range for the appliance (typically 220–240V for NZ/AU or 110–120V for North America) causes the power supply circuit to fault.
DIY PossibleFaulty wall outlet or circuit
A loose receptacle connection or a circuit with high resistance under load produces voltage drop when the compressor starts.
DIY PossibleDamaged power cord or plug
A damaged power cord has increased resistance, causing a voltage drop at the appliance terminals.
DIY PossibleMain PCB power supply section failure
The power supply regulation circuit on the main board has failed, generating Code 1 regardless of incoming voltage quality.
Requires ProfessionalSafe Checks You Can Do
-
1
Check the power outlet
Plug a lamp or another appliance into the same outlet. If it also flickers or behaves erratically, the outlet or circuit is the issue rather than the refrigerator.
The refrigerator should be on a dedicated 15 A or 20 A circuit — sharing with other high-draw appliances can cause voltage sag on compressor startup.
-
2
Test outlet voltage
Use a multimeter or plug-in voltage meter to verify the outlet voltage is within the appliance rated range. Measure during a compressor start if possible.
Voltage below 108V or above 132V (for 120V appliances) is outside the acceptable operating range.
Tools required -
3
Inspect power cord and plug
After unplugging, inspect the power cord along its full length for cuts, kinks, or heat discoloration, and check the plug prongs for burn marks or corrosion.
Discard and replace a damaged cord immediately — do not use the appliance with a damaged power cord.
When to Call a Professional
Contact a qualified technician if:
- Household electrical circuit problems require a licensed electrician
- Main PCB power supply section failure requires board replacement
- Persistent voltage faults with a good supply suggest internal board fault
