Michael H Nashua , NH May 10, 2015 Appliance: Frigidaire Gas Range FGGF305MKFH Frigidaire Range Fggf305mkfh: Short in electrical control. How to replace Control Board. Removed the upper back panel (6 hex screws), removed control unit (4 phillips screws), changed all plugs from bad unit to new unit and attached in reverse order to the removal. Used a 1/4" socket set, but nut driver would have worked too. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
