It's sad that the motors are so expensive. Okay, so they're relatively high voltage, but brushless motors aren't exactly a new or expensive technology. You should send Clive one to dig into for fun, if you haven't already.

Be thankful that they use a hammer to defrost, last week I got the privilege of paying for the repair of a coil defrosted with a screwdriver.

I've seen that so Many times... But only once on a CO2 system xD

For being so expensive, they should at least be IP67 classified, so you can rinse these motors of without any problems. I don't get it why manufacturers don't know that a freezer can freeze up and needs to be rinsed with hot water to get it back working in a reasonable time - it is to be expected so they should put proper motors in.

Sadly these are built down to a price, rather than up to a specification.

I suggest retrofitting with KE2 defrost controller, door switch auxiliary and KE2 Smart Access.

Chris, I've seen situations where the manufacturer of equipment will have motors or parts made to their spec so that one needs to get the parts from them. This only makes service calls more expensive for parts, and can delay repairs since they usually have to order the parts rather than being able to stop at an HVAC supplier and get it off the shelf.

I have worked in hospitals and they put their frozen food in the cooler before cooking the next day

I very much appreciate all the info you provided in your video’s. I enjoy watching and learning how you approach each call, even if you think your cheating a little bit with some of the diagnosis. It allows us to to see and decide how we can approach the same situation. Keep up the great video sir

Amazing 👏 craftsmanship Thank you for sharing your knowledge 🙏 respect 🙏

2:39 I got a couple of those for the garden hoses at home. Wife loves them, worth every dollar. Tough as nails and good options for everything from defrosting the deep freeze in the shed to washing the dirt bikes on "flat" mode.

Wow, those motors have a damn good seal.

I've found using a flat head screwdriver to hold the bracket in place while you get the fan guard on makes it super easy.

Good vid my Bud ... Thx as always ...

Hot gas defrost with air switches. The customer probably turns the breaker off to "defrost " it.

I know of an organisation that does that to several Scope fridges. They're programmed for several defrosts daily.

I use a steamer to defrost Ice all the time.great around wiring to use and motors.

Thanks!

Today I learned you learned your trade from your dad and now a lot of how good you are makes sense

How about a hanging clear vinyl curtain in the door way?

A simple ke2 with defrost can work good to stop frost buildup

Lol we had “”3!”” Customers like that ! An we finally gave up an just decided hay!! It’s their money their poring down the drain and in to our pockets. YESsss it is extremely frustrating to the Teck on ridiculous preventable returns, but? You can drag a camel to the water hole, but you cannot force him to drink.. So I “FULLY” understand your frustrations, but ultimately it’s a customers call they own the equipment an can do however they want 🤦‍♂️ all we can do is try

Nice video, thanks 👍🙌😊👌🙏🍀

When you got there that timer had 8 defrost😮

Good job Chris.

Awesome video

Nah, I see this everyday, my customers always tell me that the coil just iced up yesterday.

I would tell these people that constantly leave the door open that your next service call will cost you twice as much. If they wanna get a discount, they must abide by keeping the door closed. I would not put up with some of the people.

The temperature in the cold room is very low and so that causes ice build up on the coils, yet some refrigeration systems use a defrost clock to tell when it’s time to heat up the ice to melt it off. it is very difficult to set.

They should use more accurate ice sensors

I just had two evap fans and defrost timer go bad but my sight glass was good and it sounded good never did put gauges on and they still running cold job was three days ago

So they just keep paying for service calls every 2-3 months instead of fixing their issues...

I had to take yesterdays video down because of audio issues

The amount of cooks and managers that think they can be technicians is comical. Some are decent due to past mechanical experience but the vast majority barely know anything.

So put in 1000 watts of defrost heaters and set it to run the first 5 or 10 minutes of every hour. Do any of these use a hot gas valve for defrost, like on ice machines?

At my company we call it “swag”… somewhat educated guess lol

Are the hammer marks rounded, if so are they using a ball-pein hammer on it?

Drip cycle, fan term, superheat! With this ice pattern, did you look at these? I suspect water is blowing off that coil on startup after defrost.

9:10 Should these motors have a sight glass to see whether they are dry on the inside or wet or burnt?

I had all 3 fans stuck in low speed. Turns out the harness has a short in the center leg

I'm pretty sure those motors couldn't get any wetter so...

👍🇺🇸💪❄️ thanks for sharing

Do you know where to find the brand of a walk-in cooler? I'm trying to look for it in my mom's store.

Wow Nidec Servo BLDC (ECM) motor.

R448? In a freezer? Nice toasty discharge

KE2 with door switch would help them out a lot !!

yep, run it until it grenades

or the defrost probe at wrong place, or at wrong stopping temp

FIXED

By making it single speed, doesn’t that make it non-compliant with California title 24?

9 Def cycles at 30-mins each ?

Do you dry off the ceiling of the box before you leave? Water has infiltrated the motor and causing it to sense a false voltage on the red leg. You have to be really careful while defrosting the evap.

Is that those new 2 speed motors? That are extremely expensive? Nvm i guess i should watch the whole video first. Yea nothing like a 1000 dollars motor. They are stupid expensive.

Never saw an ECM motor before...

I know I'm a harsh critic of some of these restaurants, but I will try.. try.. to be more loving in this comment - first of all the wiring upstairs we VERY clean and elegant. But shouldn't the manager be punished corporally for their negligence? Either terminate the manager, or make sure they train, warn, and then terminate the employee if the employees are guilty (a 50 buck camera pointed at the handle will insure the perp is caught), or at LEAST rap their knuckles with a steel ruler? Am I wrong here? Please tell me I'm wrong!

Everyone acts like its the managers fault. Its not the managers fault, it is the employees and their work ethic. I have been onsite when managers try to correct a behavior and an employee says F this and quits leaving the store short handed and shifts unfilled. The managers have to walk on egg shells for fear of losing employees even shit ones. Until the work ethic improves it will be an issue. Employees don’t care about the equipment or doing things right because they aren’t invested in it. They figure it ain’t mine who cares.

Can I buy that used motor from you? I need something like that for a project and new motors are expensive :D maybe add a extra heater on the top in front of coil.

First as a disclaimer, I will say that without the customer we wouldn’t have jobs. Now with that being said, sometimes the customers are absolute idiots. We can explain to them certain important things like “it’s important to not leave the freezer door open so this won’t happen again” or from my experience, “keep your filter regularly changed and don’t run the Tstat at 60 degrees in the middle of the night in November so this doesn’t happen again” and they still don’t get it. And they do it again and wonder why they keep having the same issue. 😂

I’d bet the person leaving the door open wants a Tesla so they can waste more energy for everyone.

If they want it fixed nothing else just do it you'll get more money coming back if they don't listen to you they probably ignore those switches
