Open Case Cooler Running Warm Master Built

Good job rick

[@SupermarketRefrigeration]

Nice job Sir 👍🏻 I agree with dumping the charge and starting new. Its so mucb easier to start off with that rather than chase your tail for 2hrs. Seems like its always those dinky little units that give us the most issues.

[@HVACRSurvival]

Thanks 👍.

[@watermanone7567]

Nice work, thanks for the video. Lots of junk came out of the coil you washed.

[@jin8684]

Just a heads up, a Dixell Universal-XR can replace any one of those controls. They usually fit in the same housing space as danfoss and masterbilt controls. I recommend carrying one if you dont currently have one on the truck :)

[@ulairecantea9231]

That is true, but you can't replace all the time controller that you are not familiar with. Dixell is really versatile and easy to use, but then, in my experience, it fails more often than True controller that Master Bilt units are equipped sometimes with.

Nice job brother!

Nice work Rick. Remind me of many blod bank refrigerators I worked on related to the defrost system on them. Simple Ranco termostats with a capillary style sensing tube directly inside the evaporator fins. 39F / + 4C and a differential of 42F / 6 C to cycle off at 28F / -2C negative😬 Those units actually defrosted in every cycle off just by the heavy airflow over the evaporator😬 Crazy short cycling periods by just a few minutes between the cycles. Worked exceptionally excellent. The Copeland condensing units used a couple of decades ago kept living 10-15 years. A very seldom time the current style start relay gave up, what a quality those days. The Ranco’s died after 5 years of switching duty😂 The temperature inside the blod bags stayed inside 0,1C the all time they was stored. System was simple and very sensitive to a rising air temperature. Thank you for all the interesting information you gives us dealing with so various equipment.😊

[@HVACRSurvival]

Thank you for sharing all the information. 🤜🤛👍👍

[@sherwinalvarez7365]

Great video, Rick. Thanks for sharing. I must say I get pissed off with the lack of definite answers dealing with all this electronic stuff. When it was mechanical, you were able to say this is the problem. Fix, replace, or order it, and you were the hero. Not so much nowadays.

[@HVACRSurvival]

I agree 💯 %

I'm an IT Consultant. Welcome to my world. I spent three months chasing one network problem, 'fixed' by separating into -two- separate networks, and still don't know what causes the issue.

Service calls are thankfully slowing down a bit....so we can get to the repairs that have been pushed back due to call volume. I have been replacing compressors left and right recently. Did a TXV to EEV conversion on a chiller.....life is different, now that I work for a manufacturer

[@HVACRSurvival]

I hear you, we’re getting bits and pieces done that’s been on standby. (Factory work etc) I kinda was hoping I’d get found on line and get recruited by a manufacture or large company. It’s never happened🙃

[@lnk4328]

@@HVACRSurvivalWith your extraordinary refrigeration/heat pump and controls proficiency, you might look at manufacturers of condensing boilers. They are now having to transition from just natural and propane, which you already know, to include heat pump technology.

[@timsky99]

it's a fridge, all it needs is an off cycle defrost and a cabinet temp set point. Manufacturers make it all way too complicated.

[@makinbac0n]

Yep. Every component added is just another point of potential failure.

[@throttlebottle5906]

that works great, in a nice controlled climate environment, without air blowing in and disturbing the air curtain. that just ruled out majority of every install, as where they're put is never controlled well and right where a vent blows or door that's open more than closed. lol

[@HVACRSurvival]

Agreed 👍

[@tbelding]

Yeah.... in the Deep South, with high humidity, high heat, and cabinets being set in draft paths, you can't be quite that simple. I just watched two stores that I visit regularly having their coolers be shut down for days, likely for something similar. (Tagged for unreliable temperatures). (Not the same chain.)

[@danfinch3963]

Nice job have notes you have done over the years...definitely came in handy. I don't know how you read that display on the bottom...I felt like it was an episode of 24 down there.

[@makinbac0n]

I would expect an open cooler to frost up when placed next to an exterior door. Especially with the humidity of the summer. Had this model at my buddys gas station and in summer we would have to defrost it manually every once in a while.

[@throttlebottle5906]

typical scenario there, installed in a bad location near a heavily used door or where a vent/fan blows into them and the building climate is never controlled well. most call for max. ambient temp around 74F and humidity below 50%

[@HVACRSurvival]

All valid points, like I said, I never heard anything more back about it still happening. Maybe it was designed to run a lower saturated suction temp to counter the open case? Not sure…I do know the air band working properly is critical to reduce the freezing effects.

[@CapsCup2012]

My man

[@ulairecantea9231]

Thanks for the great video. Regarding pulling out the previous charge, did you just leave some positive pressure to avoid vacuuming system and then add new R 404a, or did you do recovery plus vacuum?

[@HVACRSurvival]

I bring it down to just a positive vapor that way I don’t have to pull vacuum unless I think there was a reason to do it, like a massive leak that would’ve possibly sucked in air or noncondensibles.

[@ulairecantea9231]

@HVACRSurvival Thanks, Rick, for the answer

[@HVACRSurvival]

@ulairecantea9231 I actually read and try to respond 😁 I like being different that way

I've been thinking about getting that impact due to size ( I'm a home appliance tech some times my impact doesn't fit in smaller space) but worried about battery life.. My 10yr old Milwaukee lasts all day unless I use it for washer gearcases, how does that one fare?

If you could pick the equipment if you had a small walk in freezer and cooler what manufacturer would you pick for evap and roof? I know there are size differences but what manufacturer?

Bone / Heat Craft is what we use, it does well. Not to many problems
