On control panel are 3 buttons and a display
Far left....ON/OFF
Just to right is MODE
Far left.....TEMP SET
In Display are indicators of:
Auto Electric Mode-----Power cord plug (left)
Auto Gas Mode---------Gas Flame (right of power cord plug)
Manual Electric --------Power cord plug (top)
Manual Gas------------Gas Flame (bottom)
Then 1-9 temp set point
When you push hold MODE Button does it step thru the 3 different modes?
Can you select each one of the 3 different modes?
(AUTO, Manual AC, Manual GAS)
Check/verify that you have 120V AC Power available and that the outlet fridge 120V AC power cord plugs into is actually HOT. (unplug fridge power cord...plug a drill motor, a lamp etc to check that outlet works)
No AC power at outlet...check CBs / GFCIs etc
Got AC Power at outlet.
Then you need to remove control module/lower circuit board cover (outside compartment) and check the 8A GLASS fuse. (F2 position on board...lower left)
It is for the AC Power/electric heater circuits.
If blown....try a new fuse (fast acting type---not slow burn)
If new fuse blows...bad/shorted electric heat element---fridge uses 2 elements. BOTH have to function for AC operation.
IF still unable to control/select functions
Unplug:
120V AC cord from circuit board
12V DC POS & NEG Leads from circuit board
Harness connectors 'K' , 'L' and 'M'
(Check pins/slots...nothing bent etc---then plug connectors back onto board)
Wait 30 seconds then plug 12V DC leads back onto board then 120V AC plug back onto board
