GE Refrigerator Error Code H1: Start Relay or Compressor... | appliancefaults.com

Technical Background:

The H1 error code on a GE refrigerator typically indicates a compressor or compressor start-up problem. The main control unit (MCU) monitors the compressor's performance. If the MCU detects an issue, such as excessive current draw or failure to start, it will trigger the H1 error. The voltage path from the MCU to the compressor and the return path are essential for proper compressor operation.

Symptoms:

The refrigerator displays an H1 error code. The compressor may not be running, and the refrigerator is not cooling properly. There might be clicking sounds coming from the compressor area.

Possible Causes:

Faulty compressor start relay (PTC).
Failed compressor.
Wiring harness issue between the main control board and the compressor.
Overload protector tripped or defective.
Main control board malfunction.

Solution:

1

Unplug the refrigerator or turn off the breaker at the breaker panel.
2

Locate the compressor start relay. It's usually mounted on the side of the compressor. Remove the relay.
3

Visually inspect the start relay for any signs of burning, cracking, or melting.
4

Test the start relay using a multimeter set to ohms. Check for continuity. Replace if open.
5

Check the compressor windings for shorts to ground. Using a multimeter, measure resistance between each compressor terminal and the compressor body. A reading of zero indicates a short to ground. The compressor will need replacing if this is the case.
6

Inspect the wiring harness and connectors for any loose connections, corrosion, or damage.
7

If the above tests pass, the main control board may be faulty. This often requires licensed technician diagnosis and replacement.

Safety Warning:

Disconnect power to the refrigerator before attempting any repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental energization. Refrigeration systems operate with high voltage (120V AC) and potentially hazardous refrigerants. If unsure, contact a qualified appliance technician.

Prevention:

Clean the condenser coils regularly (every 6 months) to ensure proper heat dissipation. Avoid overloading the refrigerator, as this can put extra strain on the compressor.

Expert Tip:

Some GE refrigerators have a service mode. Refer to the service manual for your specific model to access diagnostic tests and error code history. Often, entering service mode involves pressing and holding specific buttons on the control panel simultaneously for a few seconds. On some models, you can press and hold the freezer temp DOWN and the refrigerator temp UP buttons simultaneously for about 3 seconds to enter the service mode.

Frequently Asked Questions

•What is the correct ohm reading for a good compressor start relay?

Typically, a good PTC start relay will have a low resistance, usually between 3-25 ohms when measured across its terminals at room temperature.

•How do I properly discharge a capacitor before working on the start relay?

Use a properly insulated screwdriver with a resistor to short the capacitor terminals. This discharges any stored energy and prevents electrical shock. Make sure the screwdriver handle is fully insulated.

•Where can I find the service manual for my specific GE refrigerator model?

You can usually find the service manual online by searching for the model number and "service manual." Websites like AppliancePartsPros.com or searspartsdirect.com often have service manuals available for download. You may also find it on the GE Appliances website.
