GE Refrigerator Error Code H1: Cleaning Condenser Coils... | appliancefaults.com

Technical Background:

The H1 error code on a GE refrigerator typically indicates a problem with the condenser fan motor circuit. The main control unit (MCU) monitors the voltage and current draw of the condenser fan motor. If the MCU detects a fault, such as a stalled motor or no voltage, it will trigger the H1 error and shut down the cooling system to prevent damage.

Symptoms:

The homeowner observes that the GE refrigerator is not cooling effectively, and the H1 error code is displayed on the control panel. They may also hear unusual noises coming from the back or bottom of the unit.

Possible Causes:

Blocked condenser coils
Faulty condenser fan motor
Condenser fan motor wiring issues
Defective main control board
High ambient temperature

Solution:

1

Disconnect the refrigerator from the power outlet by unplugging it or switching off the breaker.
2

Locate the condenser coils, typically at the rear or bottom of the unit. Use a vacuum cleaner with a brush attachment to remove dust and debris.
3

Inspect the condenser fan motor for obstructions. Manually rotate the fan blade to ensure free movement. If the blade is stiff, replace the motor.
4

Using a multimeter, test the condenser fan motor windings for continuity. A reading of infinity indicates an open winding and motor replacement is needed.
5

Check the voltage supply to the condenser fan motor using a multimeter. You should read approximately 120V AC when the compressor is running.
6

Inspect the wiring harness to the condenser fan motor for any loose connections or damaged wires. Repair or replace as necessary.
7

If all other components test good, consider replacing the main control board. The H1 error could be triggered by a fault in the control board’s fan motor circuit.

Safety Warning:

Always disconnect the refrigerator from the power source (Lock Out/Tag Out - LOTO) before performing any repairs. High voltage is present in the control panel and wiring. Use extreme caution.

Prevention:

Regularly clean the condenser coils every 6 months using a vacuum cleaner. Ensure proper ventilation around the refrigerator to prevent overheating.

Expert Tip:

Many GE refrigerators have a service mode that allows you to manually activate the condenser fan motor for testing purposes. Consult the service manual for the specific model to access this mode. This can help isolate the issue to the fan motor or control board.

Frequently Asked Questions

•What is the resistance value I should see across the condenser fan motor windings if it's good?

Typically, a good condenser fan motor will have a resistance between 50 and 150 ohms, but consult the specific model's service manual for precise values.

•If the condenser fan motor is running, but the H1 error persists, what should I check next?

Check the thermistor connected to the condenser fan circuit. An inaccurate thermistor reading can trigger a false H1 error even if the fan is operational. Also, double check the wiring harness for corrosion.

•How do I access the service mode on this GE refrigerator to manually test the condenser fan?

Service mode entry varies by model. Usually involves pressing a specific sequence of buttons on the control panel (like Freezer Temp Down, Fridge Temp Up, Freezer Temp Down) within a short time frame. Refer to the specific model's service manual or online resources for the exact procedure.
