Electrolux Refrigerator Error Code 22

Error code 22 indicates that the control board is detecting an open circuit from the NTC thermistor located in the Perfect Temperature Drawer. This thermistor is responsible for monitoring the temperature inside that compartment and sending data to the control board. When the circuit is open, the board cannot receive valid temperature readings and flags the fault. The most common causes are a failed thermistor, a loose connector, or damaged wiring.

The Perfect Temperature Drawer may not maintain its set temperature accurately while error code 22 is active, since the control board has no valid sensor input to regulate that zone. Food stored in the PTD could be at risk if temperature control is compromised. Other sections of the refrigerator may continue operating normally, but the fault should be diagnosed and repaired promptly to avoid food safety concerns.

A power reset may temporarily clear the error code from the display, but the fault will return as soon as the control board re-checks the PTD thermistor circuit and detects the open condition again. A reset does not repair a failed thermistor, broken wire, or loose connector. The underlying cause must be diagnosed and corrected before the code will clear permanently.

A knowledgeable DIYer can address this code by first checking the thermistor wiring harness and connectors for any visible damage or loose connections. If the connections look intact, testing the thermistor resistance with a multimeter and comparing it to the temperature-resistance chart will confirm whether the sensor has failed. Replacing a thermistor is generally a straightforward repair, but if the control board is suspected, professional service is recommended.

If only the NTC thermistor needs replacement, parts typically range from $15 to $50 depending on the specific component, and labor costs for a service call generally range from $80 to $150. If the wiring harness requires repair or replacement, costs can be somewhat higher. A control board replacement represents the most expensive scenario, often ranging from $150 to $350 or more for parts alone.
