Not a Bandito  -Just me wiping off the sweat

Not a La Frontera Bandito -Just me wiping off the sweat. Honest.

Only in Texas can you get snowed on and sunburned in the same day.  Weather extremes are justa kinda given  down this way. Yesterday marked the first day  the water heater was unnecessary  for a shower….. which means it is just danged hot down here in South Texas.  I watch all the rig boys, roughnecks and pipeliners going in and out the gate and just wonder how it is they are able to survive in this scorching heat.  My outside schedule is much abbreviated.  I try to have all of the piddling around the RV completed no later than 9am.  After that, I retreat to the shade of the awning.  If it all works out good, I get to stay there the rest of the shift with the comfy chair and water bottles handy.

One of the piddling projects I had on the To-Do list was some sort of decent siphon hose.  I bought this contraption off of Amazon that has some sorta brass slider thing inside the hose and supposedly if you manipulate it just right, that slider thing acts like a piston and starts the suction.  It worked  like ass.   Back in the day, we just used to slice off a piece of green garden hose, run it down the tank , give it a big ol’ suck and let it run.    If you got a mouthful of diesel or gas it was just the way it was.  I try not to live like that anymore.  Work Smarter. Not Harder.

What I came up with works damn good.  I got a marine primer bulb, Attwood Primer Bulb, some Gates 3/8″ Fuel Line and a couple of stainless steel hose clamps.  I put 5′ of fuel line on the inlet side and 2′ on the outlet side; just make sure you have the arrow on the primer bulb pointing the right way.  Gotta say it works darn good and all the pieces were Made in the USA.   I coiled it up all nice and neat, secured it with a velcro zip-tie and threw it in the back of the big ass Suburban.  Mark another piddler off the list.

Karma always catches up with you in the end, don’t it?  This is the time of year when the RV crowd is complaining about stinky black tanks, AC units that are inadequate and refrigerators that don’t cool.  I would read those posts with a certain amount of smugnicity.  The Old Girl had plenty of BTUs to keep us cool on the hottest South Texas day, the black tank smelled like Purple Sage after a rain (mostly) and the ancient Norcold ‘fridge kept the cold beer icy.  I damned sure took that old Norcold for granted.  It was spacious and the adjustable thermostat made it easy to adjust the temp up a little in the Winter and down a tad in the Summer.   The freezer wouldn’t keep the Blue Bell ice cream froze but I could live with that.

Fast forward 17 model years and you have the Princess Palace.  You would just figure in 17 years, those RV engineers up in the Midwest would have pretty much figured this RV biz out, right?  I do believe ’bout all they have figured out is where they can cut a corner here and there and then still sell it to us.  Don’t get me wrong—- the Princess Palace is a definite upgrade compared to the Old Girl.  None of us would go back to the old RV given a choice between the two.   One of the problems is the Dometic DM2652 refrigerator.  The more I discover about it, the more I gnash my teeth and pull my hair.   It is tiny– two soda cans barely fit back to back on the top shelf.  I keep a fridge thermometer in there just to make sure the mayo don’t go bad and the first of the week I peeked at it and it said 60 degrees.  WTF?  I slid the thermistor all the way to the top of the cooling fin and hoped the temps would come down.  No Bueno.  Now, here is where I have a huge problem.  The DM2652 has automatic temperature control — no adjustable thermostat.  Some engineer figured out the best temperature for my beers and that’s that.  I think that sucks.

At any rate, I had a fridge going tits up PDQ and I had to figure something out. BTW, a new DM2652 is about $1200– as if!  I would rather tie a chain to the sorry sumbitch and jerk it out into the middle of the lease road as buy another one.  The maintenance manual says to unplug the thermistor lead from the control board to determine if the thermistor is bad or if the cooling unit itself has gown south. The manual says depending on ambient temperature the fridge temp should go to ~ 43 degrees with the thermistor disabled.  This means the cooling unit runs ALL the time with no thermostatic control………….  and 43 degrees is as cold as you are gonna get. Sorry folks but I think that is sorry as hell.  43 is not cold enough to suit me.

I unplugged the thermistor and the black pipes in the Dometic guts immediately started to get hot.  6 hours later the interior of the fridge was setting at 44 degrees.  Bad news is I have a bad thermistor. Good news is the cooling unit is working –such as it is. Bastards!

It appears this thermistor failure is all too common on many Dometic models.  To the point there is an aftermarket thermistor replacement where you cut the tip off the thermistor and replace it with a user adjustable thermistor.  Well, I am all over that as you could well figure.  I ordered one up and we will see if it gives me some relief.   In the meantime, Miss K is shopping for a nice mid size 110v fridge to do the heavy lifting around the Nomad Camp.   The Damned Dometic should be good for the Greek Yogurt and V8 Juice I reckon.

 

End Note:  One Day at a Time by Donna and the Buffalo from the Tonight, Tomorrow and Yesterday cd.   I can’t put my finger on just why I enjoy these folks but I do.  Think Pure Prairie League/ Marshall Tucker Band  with a Millennial fusion.

    I just bookmarked the thermistor replacement, thank you … with my old Dolphin I am always in need of something. You probably already know, but if you need a control board the Dinosaur boards have a temperature adjustment build-in. Although you do not operate on propane very often, the Dometics connections seem to be sensitive to corrosion on the gas circuit. Often when we get ready to travel, the gas side will not fire … spray of Dexoit on the connectors will fix it.

    Ya might think about getting a 12 v circulation fan that mounts in the refer vent and circulates air through the coils. I got one and it improved cooling a bunch. Some are thermostat controlled and some use a computer fan with a switch.

    This is just UNACCEPTABLE!!!
    It is hard enough to cook gourmet meals with <2SQ FT of fridge SPACE.
    Now I gotta contend with 60 degree temps.
    This is just NOT copacetic.
    When is that new filtered water in the door fridge arriving????

    Dometic fridges are for the birds–I have the same problem with one in my 5th wheel here in FL. Thanks for the info.

    We are still having that same problem that started in March while GG in TX. We got a new thermistor but after a few days, temps went back up to 60. Glad we had our extra dorm frig! We are thinking about putting an electric frig in, forget a new Norcold/Medic. Too much money!
