lobi Posted August 22, 2016 Report Share Posted August 22, 2016 Found a great post in where op finally discovered that the small inside (above the fridge) control board was bad with no led lights and non working fridge. I may have this same problem but found sonething else. In poking around from the outside of the fridge to check connections and fuses, I found a stray wire that isn't connected to anything. It is blue and comes from a connector near the top left of the outside control board. It is a Dometic RM2652 Can someone with the same unit (or knowledge) tell me if this wire is supposed to be connected to something. I've tried to attach a pic, hope it worked. Thanks! ~lobi I've spent most of my time hunting and fishing, the rest I just wasted. Link to comment Share on other sites More sharing options...
Yarome Posted August 22, 2016 Report Share Posted August 22, 2016 Not enough info to determine why your reefer isn't working, but the blue wire is your test point wire and shouldn't be connected to anything. To confirm.. it should be tied into the p1-2 position in your control board wiring harness. Link to comment Share on other sites More sharing options...
BIGMIKEM Posted August 22, 2016 Report Share Posted August 22, 2016 Yarome is right, i just visually checked my 2652 and mine is disconnected on the one end also, good luck Link to comment Share on other sites More sharing options...
lobi Posted August 22, 2016 Author Report Share Posted August 22, 2016 Thanks Yarome. I didn't burden with all the info to determine fault but rather just looking for answer to the stray wire. I'll drop back to the post involving diag and solution being the brow panel circuit board. Thank you also BigMike for the effort and visual check.

Kirk W Posted August 22, 2016 Report Share Posted August 22, 2016 I suggest that you start by downloading a copy of the service manual from Bryant RV's website. If you dig far enough you can find some diagrams that show a blue wire. Good travelin !...............KirkFull-time 11+ years......

oldjohnt Posted August 23, 2016 Report Share Posted August 23, 2016 FWIW My RM 2652 works fine, and same as other postings, also has that "blue wire to nowhere" (or at least not connected to some terminal) as shown on the top right corner of the diagram.

Wrknrvr Posted August 23, 2016 Report Share Posted August 23, 2016 The blue wire you are talking about is not used unless the RV has a energy management system. And then I have not seen on of them connected. This should get you at least looking the correct direction. Safe Travels, Vern Link to comment Share on other sites More sharing options...
jimhanus Posted October 25, 2016 Report Share Posted October 25, 2016 According to what I have read, and seen on the drawing, the blue wire is only a test point. Link to comment Share on other sites More sharing options...
