Dometic fridge DM2852 No power

[sgfrye]

Ok am I missing something. My dometic DM2852 was running fine on this past weekends trip. Get home no power on 120 or dc. No lights on display, interior light nothing. What I’ve done so far:

Used multi tester on dc terminal block shows 13.7 volts. House battery is 1 12volt tests fine.

110 v outlet fridge plugged into cks out ok

Checked 3amp and 5amp fuse on control board checks ok with a “green light led” fuse checker.

Am I missing something or is next step replacing control board?

As always thanks!

:W I am tempted to re-quote the whole thing again and go for a record.

My problem is the thermal fuse

The thermo disc pop out on mine did not trip.

Im buying a thermal fuse only not the 61 dollar part you linked. I will install fuse where i removed orginal fuse. Couple bucks for just the fuer

The WIRED Thermal fuse is a FLAME fuse. If the unit catches fire from a leaking Cooling Unit AT THE BURNER, the flames melt/burn that Thermal fuse and shuts power down to the refer. In the 15 or so years since Dometic started installing that wired Fuse, I have NEVER had one fail. Doug

Their in lines the real issue.....
It only shuts down power to fridge AFTER A FIRE.

:S

NO, It kills power to the Fridge when the fuse melts. With NO source(LP flame) to keep the flame GOING, the flame snuffs out. You can have a BAD flame from a dirty burner and/or rodent/insect nests that would cause a flame flare out of the burner area and that fuse would shut down the refer also. Doug

Your words (highlighted)......and I responded to those

OK, lets state this. You have a Fire suppression system in your Auto or house. You complain that it only functions AFTER a fire starts:B Doug

PS, THAT is the PURPOSE of that Flame fusible wire. To STOP the source of the flame.

The Thermal DISC on the burner outer stack cover was installed as part of the original Dometic recall. BUT, ALL Dometic refers built after the start of the recall have those Thermal DISC's, NOT a fuse. Some you can reset and the others when they trip you replace. Doug

PS, when they trip does not mean you have a bad cooling unit. I have yet to find a BAD Disc and a BAD cooling unit as the cause.

[BFL13]

Thanks, I think it must be the recall.

Please clarify the size, type, and location of the "thermal fuses". I can't find them on my S630 or in the RM2852 manual. Just the 3a on the main board for 12v. Is it inside the "ignition module"? Thanks.

Is it this "recall fuse" business, so that's why I can't find one on mine?

i believe so.

someone else may post the info sooner but if not i will take a photo to show location, and get fuse info. it is inline on red wire behind the chimney, coming out of chimney popup breaker, folded and on a small bracket, covered by a black moveable covering.

my fridge in a 2018 model.

the thermal fuse is not shown in my original owners manual, downloaded service manual, or parts list manual.

Thank you for reporting back.
