Blockages are as hard as a weld and are attached in the upper coil area and CANNOT be broken loose. So, burping just rearranges the Ammonia temporarily to work a little longer. It works but NOT AS WELL AS BEFORE THE BLOCKAGE. IT WILL FAIL AGAIN. Rebuilders cut out the tubing where the blockage is on blocked units and then weld a new upper tube assbly in place, then charges the cooling unit. THERE IS NO WAY THAT MOBILE TECH FOUND A BLOCKAGE, UNLESS HE STUCK AROUND FOR 2 OR 3 DAYS AND DID VARIOUS TESTS. TEMPORARILY UNBLOCKING A UNIT REQUIRES THE REFER TO BE TURNED UPSIDE DOWN FOR 24 HOURS AND THEN RIGHT SIDE UP FOR 24 HOURS. Then start a cooling process. You could have just had a glitch and if the refer continues to cool (below 38 degrees in the refer and below 10 degrees in the freezer), I would not worry about it. Also, it could have been as simple as the rear cooling fans did not run. Did the Mobile tech checked those? Doug

PS, is the refer in a slide room?

If you plan on living in the RV.. Do you plan on MOVING it or parked on/near construction of new house site.

If the latter.. Consider the "new Fridge" for the new house... Have it on hand.. (You need not unbox it unless you fear warranty expiring) If the RV fridge fails.. Unbox. plug in and use.. Or better (less energy needed to run it) Use it instead of the RV unit... And when new house ready.. MOVE IT.


Home was where I park it. but alas the.

The tech used a heat measuring gun and found the top tube hot on the left side and it cooled off right in the middle and continued cool the rest of the loop. Seems logical to me that where the heat stopped and the cool begin theres the problem.
The fridge is in a slideout. One of the fans was stopped up with mud dobbers nesting on it. Once flipped, it gurgled a few minutes and then we flipped it right side up. powered up and working still. Steady 34 degrees in fridge.
Note: we were camped in Davis Mountain State Park and temps got down to single digits a couple of days before it quit working.

thanks

AS I stated, NO BLOCKAGE. The fan was the problem. Also, to make the refer operate BETTER, I install an additional 12 volt cooling fan at the upper outside vent door blowing OUT. This is really needed for all slide room installed refers. IF any blockage, you would NOT get 34 degrees. The heat gun showed high temps because with inadequate ventilation the cooling unit overheated slightly. Doug
