my 1210 iM keeps blowing the 5amp dc fuse

my 1210 IM norcold fridge works great with no problems until the weather gets cold . As soon as the temp goes down to 5 or 6 celius the 5 amp dc fuse blows .If i take a hair blower and heat the back of the fridge up and replace the fuse it works for a while . I checks voltage in and it is good ,am wondering if i need to replace board , any help would be appreciated .

    Hi,

    Add a 60 watt light bulb and a TC-3 thermocube to the outside of the fridge. Restrict the airflow leaving only one set of vents open. Use duct tape on the inside of the access hatch.

    Norcold does sell a cold weather kit--but the light bulb works just fine.

    That fuse protects the board from DC items on the refer that could destroy the board.
    1. The Cooling fans(Most likely)
    2. The tstat for the cooling fans
    3. The inside optical board(On/off/temp set) and the wiring going to it
    4. The LP solenoid valve
    5. The heat strip for the optional icemaker line to the icemaker
    6. The bottom inside refer doors divider strip heater
    7. The interior light bulb assbly
    You need to check the DC items before you spend money on a Board. I cannot remember EVER replacing a Board for the 5 amp dc fuse blowing. It has always been something on the Load side. Doug
