How do I fix the H1 code on my Frigidaire refrigerator?

The H1 code on a Frigidaire refrigerator indicates a communication error between the control board and the display panel. To fix this issue, you can try resetting the refrigerator by unplugging it from the power source for a few minutes and then plugging it back in. This can often resolve minor communication errors.
If the H1 code persists, it may be necessary to check the wiring connections between the control board and the display panel. Ensure that the connections are secure and free from any damage. If the problem persists after these troubleshooting steps, it is recommended to contact Frigidaire customer support or a qualified appliance repair technician for further assistance.
