Pr Er

Pressure Sensor Error

Severity

High

When a Whirlpool Refrigerator shows Pr Er on its display, the internal diagnostic system has flagged a condition known as "Pressure Sensor Error". Most repairs for this code are straightforward and can be completed at home.

Owner's Summary

This error relates to the sealed refrigerant system inside your refrigerator — not something a homeowner can safely diagnose or repair. Refrigerant handling requires EPA certification and specialized equipment. This is one of the few refrigerator repairs that genuinely needs a professional.

Symptoms

Whirlpool refrigerator compressor cycling abnormally, Pr Er displayed

Common Causes

Faulty refrigerant pressure sensor
Low refrigerant charge
Sensor wiring fault
Compressor or sealed system fault

How to Fix

1 This typically requires a certified technician with refrigerant handling certification
2 Do not attempt to access the sealed refrigerant system yourself
3 A technician will check pressure sensor function and refrigerant charge level
4 Sealed system repairs require specialized recovery and recharge equipment

Tools You'll Need

Screwdriver Set Bubble Level Replacement Gasket

Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.

Technical Explanation

Pr Er indicates the refrigerant pressure sensor — used to optimize compressor efficiency and detect potential refrigerant leaks — is reading outside expected operating parameters. This can indicate sensor failure or, more seriously, an actual loss of refrigerant charge from a leak in the sealed system.

Is It Safe to Keep Using?

Significant food safety risk if cooling capacity is compromised. This requires prompt professional diagnosis — refrigerant work cannot be legally performed without EPA Section 608 certification.

Technician's Pro Tip

Unlike most refrigerator faults, this one genuinely requires a licensed technician — refrigerant recovery, leak detection, and recharging require certification and specialized tools that go well beyond typical DIY appliance repair.
