Frigidaire Dryer Error Code E92

E92 indicates a communication protocol incompatibility between the Electronic Control Board and the Interface Board on push-button model Frigidaire dryers. The two boards cannot establish proper communication because they are not matched to each other. This code typically appears after a board replacement where an incorrect part was used. Resolving it requires confirming that both boards are the correct, compatible parts for your specific dryer model.

Resetting the dryer will not clear E92 because the error is caused by a hardware incompatibility, not a temporary software glitch. Each time the dryer powers on and the two boards attempt to communicate, the mismatch will be detected again and the error will return. The only way to resolve E92 is to ensure the correct, compatible boards are installed.

The cost depends on which board needs to be replaced. Interface Boards typically range from $40 to $120 in parts cost, while Electronic Control Boards can range from $80 to $200 or more, depending on the model. If a technician is performing the repair, add labor costs on top of the part price. If only one incorrect board was installed, replacing just that one component should resolve the issue.

If you are comfortable identifying part numbers and working with appliance control boards, you can resolve E92 by verifying that the correct Interface Board and Electronic Control Board are installed for your model. Cross-reference the part numbers on each board against your dryer's model number. If one board is incorrect, replacing it with the proper part should clear the error. If you are unsure about identifying or replacing control boards, a qualified appliance technician can perform this diagnosis.

A dryer displaying E92 will not operate normally because the control boards cannot communicate with each other. Attempting to run the dryer in this state is not recommended, as the control system cannot reliably manage the cycle. The dryer should remain out of service until the correct boards are installed and the error is resolved.
