Sometimes if it’s not a huge expense I will just do improvements without getting the customer onboard, because most customers have no clue what we’re talking about in reality. Especially if I can bundle it with a bigger repair. Manufacturers have a minimum standard, but when it doesn’t work in the real world, we get to make it right. So budget the waterproofing of the control in & get an approval when a bigger repair is needed, but don’t spell out the waterproofing part. When you quit replacing the controls all the time, if anyone is paying attention, you will have under promised & over delivered, worst case scenario. Thanks for the excellent videos as always Chris!
Those Danfoss controllers are notorious for bad evaporator probes. They get way out of range in a short period of time. The company I work for is the Delfield warranty contractor in our area. We carry the Danfoss controllers with probes on our truck stock. Some of the new units will need probes replaced in less than a year. Its odd because some units will run for years with no controller or probe issues. While others need new probes almost once a year. We always do probes and controllers at the same time. Great video, showing the probe replacement, my first time I used a lot of cuss words. LOL 😂
Yeah I do a ton of their warranty work too and we do the same thing by changing the control and probes. This box was actually still under warranty but the water damage voided it.
You got to love the ones with the drawer assembly’s and two frozen evaporators. I always take a picture of the way the food is arranged in the drawers before I empty it out. I had a customer get mad when i put the products back in the wrong places. I always ask if they would empty it out but most expect us to do it. I see a lot of units where the customer will leave product in the cold rail all the time, the ice buildup is ridiculous. I download the operation manual and show them where the manufacturer specifically says to shut the cold rail off at night and unload the rail for defrost. One chain restaurant refuses to defrost or empty cold rail. So the cold rail tubing will separate and the units run almost constantly. Then they want to know why these units are failing. LOL. Oh boy , some people are hard to reach.
Dave I like both those units too, techs bitch about them but the way I see it is they are easy money! The problems are predictable and pretty easy to fix
HVACR VIDEOS and the build quality is better for the customers. Not to many up here anymore most restaurants here are privately owned and they will not spend extra money on good units.
Yeah I do a bunch of chain restaurant work so most everything I work on is Delfield and Manitowoc these days. I dont run into too many traulsen units anymore.
I have a compact Delfield refrigerator that was getting too cold. I had it on the warmest setting. Seemed to be stuck on. Replaced the temp controller and got the same result. Then I found the fan cover near the condenser coil was very dirty and cleaned it. Now the temp is steady just under 40 degrees. Why did cleaning that cover help?
Hey I’m new to your channel and I definitely find the videos to be very informative and fun to watch. what would you recommend to a person trying to get into the commercial and refrigeration side of hvac. I’m somewhat new, I’ve been lead installing residential equipment and duct for 2 years and have a little bit under 1 year refrigeration exp.
hey chris much respect bro just need to confirm something here i notice that your Pressure i.e. Vsat temp Target were a little higher than those set on Walk in freezers is this because of the application of the refrigerator itself demands these targets?
Sounds like a water proof electical box is the solution. You have no doubt told the customer this. But if they wont let you take care of it, their wish is my command, huh?
so you have a stat control for the lower half and low pressure for the top. why have a low pressure control for the rail. just add a second solenoid and they both work on t-stat control. very simple solution. or is that the recommendation you made and they will not listen..

Very good explanation about the two different sections to this unit and how they work.
The lost art of knots & loops in the cables to prevent pulls. Love it.
Awesome video, Chris. Thanks for posting.
Thanks for watching
Great job on explaining how it operates 👍👍👍

Yeah I deal with the same crap with the cold rails. What state are you in?
Alabama
It's a bummer changing those probes on the low boys. Great video
Thanks bud, and yes it really sucks on the reach ins that are built in.
Glad I found this. I have many delfield as of lately with bad T-mistors I need to install. Not looking forward to it.
Thank you for your Videos I watch them all the New Tech.
Chris- thanks for the tips. I work the same way you do.
Great information as usual can’t wait for the next one 👍👍👍👍👍👍.
Thanks bud!
Good vid Enjoyed keep posting 👍👍👍😎
Right on brotha!!👍🏼🤙🏼🤘🏼 Always excellent info. 👍🏼🤙🏼🤘🏼
Thanks bud!
Great video.
Defied and Traulsen the 2 best unit in my opinion. 👍

just need to confirm something here

nice video , i just got the Fieldpiece Gauges how do u like them
I love them, get the measure quick app it works with them and makes them better
I do the knot trick also.
Why leak check if you ain’t even put your gauges on.....?

ETC AND TIME CLOCK WOULD DO THE TRICK hahaha
Yeah it would work, But the constant cut in control is a defrost clock and a temp control in one small controller.
HVACR VIDEOS yeah true those controlers are so sensitive ive also experienced if they are set higher then 4 they freeze that coil
Way to complex control! Evap is to small.
Yes, a constant cut in (5*c) little mechanical t/stat would be simple and easy to control solenoid for the lower section..they work for ages...
