As a self proclaimed 'Handyman' I often learn TONS from my mistakes. The latest mistake was thinking i could make a shore power cord for my 5th wheel using the 30A outlet normally used for my welder. WRONG!! Needless to say, this created a 220V situation that the RV did NOT agree with. Now the microwave has no function other than the light coming on and the turntable turning when the door is opened (weird), the fridge is apparently dead, and the converter is suspect. Finally my QUESTION.... : Can the circuit board on the fridge be replaced to correct the dead fridge issue? All 3 of the fuses that I can find on the fridge are intact, so I am not sure a circuit board swap would do anything. I still have power (120V) at the outlets that each of the appliances are plugged into, so i know it is no longer a power SUPPLY issue. Any suggestions (other than permanently hanging up my Handyman hat)?
