It addresses common failure modes such as unresponsive controls, error codes, and loss of function across one or more appliance systems.
This main board kit is suited for residential appliance repair applications where the original control board has failed due to age, power surge, or component wear. It is intended for use by qualified service technicians familiar with appliance control board diagnostics and replacement procedures. Specific compatible model numbers were not included in the available product data, so technicians should verify fitment against the appliance model and service documentation before ordering.
Designed as an OEM-style replacement main board kit for compatible ELECTROLUX and Frigidaire branded appliances. Technicians should confirm fitment using the appliance model number and manufacturer service documentation prior to installation.
Main board replacement should be performed by a qualified appliance service technician. Disconnect power to the appliance at the breaker or by unplugging the unit before beginning any disassembly.
