Re: Fridge only runs on shore power now
Here is a trouble shooting guide for your fridge:
1) Turn power on and turn thermostat to "7" position (Go to #2)
2) Is the compressor running? (put your hand on top to feel slight vibration to be sure). If Yes-Go to #14. If No-Go to #3
3) Is the DC Breaker is in the "on" position & optional fuse is good?
If Yes-Go to #5 If No-Go to #4
4) Replace fuse if bad or turn breaker "on". Does fuse or breaker blow?
If Yes-Go to #6 If No-Go to #5
5) Check voltage at the refrigerator "+" & "-" terminals on the black module. Is it over 12 VDC? If Yes-Go to #7 If No-Go to #6 - (Go to 17 on AC/DC models)
6) Check batteries, wiring and connections to the refrigerator for fault, corrosion, proper wire sizing and correct the problem. Go back to #1
7) Put a jumper wire between terminals "C" & "T". Is the compressor running now? If Yes-Go to #11 If no-Go to #8
8) Disconnect power. Remove electronic module (philips screw beside terminal designation label will require removal). Disconnect the plug. Measure resistance (ohms) between each of the three compressor terminal pins. Is the measured resistance APPROXIMATELY the same?
If Yes-Go to #9 If No-Go to #10
9) Replace Electronic Module. Go back to #1
10) Have compressor replaced by qualified appliance technician who has the ability to evacuate and recharge the system. This is seldom necessary so please be sure and if possible contact manufacturer for further instruction beforehand.
11) Check wiring to thermostat with ohm meter to ensure there is continuity. (No broken or damaged wires or connectors). Is the wiring okay?
If Yes-Go to #13 If No-Go to #12
12) Disconnect power. Repair or replace wiring as necessary. Go back to #1
13) Replace thermostat. Go back to #1
14) Is the fan running? If Yes-Go to #16 If No-Go to #19
15) Provide extra ventilation (ie. hatch open, Lazerette open - where air can escape). After an hour is it refrigerating?
If Yes-Go to #16 If No-Go to #19
16) Maintain that adequate ventilation has been provided. Add ventilation as required.
17) Have a qualified appliance technician determine if there is a refrigerant leak or a compressor with a mechanical problem.
18) Check voltage at "+" and "F" terminals. Is there 12 VDC (or 24 VDC)?
If Yes-Go to #19 If No-Go to #5
19) Replace fan.
From 20 to 27 Applies to AC/DC Modles Only!
20) Switch DC breaker off and AC breaker on. Does the refrigerator run?
If Yes-Go to #18 If No-Go to #19
21) Turn DC breaker on and check DC voltage on Terminal Block located on side of grey AC power supply. Is it above 12 VDC (or 24VDC)?
If Yes-Go to #24 If No-Go to #6
22) Check fuse on grey AC power supply (4 amp 110V and 2 amp 220V). Is the fuse good? If Yes-Go to #22 If No-Go to #20
23) Remove power supply and determine if there are any indications of a short circuit. If no, replace fuse. Does fuse blow again?
If Yes-Go to #24 If No-Go to #21
24) Check DC voltage output of power supply at black module terminals "+" & "-". Is it above 12 VDC (or 24 VDC)? If Yes-Go to #18 If No-Go to #24
25) Is 110V (or 220V) available at the AC plug?
If Yes-Go to #21 If No-Go to #23
26) Check plug, wiring, breaker, shore power or genset for damage or fault. Repair or replace as required. Go to #17
27) Replace grey AC power supply
I hope this helps. If not, I'm sure there are a bunch of vendors that will be willing to sell you a new fridge.
If it is the power module, let me know. i'll send you the link of where I got mine (if it's not available here on iboats). 3 days for shipping and it was here.
You might want this as well...it's the wiring diagram for the Power Module.
