First, thanks for all the feedback!

This morning, I started all three conveyor ovens. I monitored inlet gas pressure to the middle oven. After reaching operating temperatures, with 6 convection...

I can’t put my eyes on “the fairly long run”, but I’m guessing 20’. The ovens aren’t used during the summer, but I get what you’re saying. No, I don’t believe it’s a dedicated run because this is in...

Here is what’s shown in the manual. Notice the requirement for 1-1/2” gas supply to the manifold. The gas supply going to our manifold is 3/4”. The 3/4” gas line runs about 10’ to above the ceiling...

We had new triple stack XLT 1832 conveyor (pizza) ovens installed last April. Up until last week, they were working fine. Then, suddenly, the pizzas coming out of 2 of the 3 ovens that are being used...

Regardless if I have the proper inches of water column for inlet pressure and manifold pressure, would an improperly size natural gas line run feeding the appliance potentially cause issues? What...

Well, I tried insinuating in my OP that I covered all bases when I said, “(E)verything I’ve checked is not pointing them to any other components or refrigerant issues.” I guess I didn’t do a very...

I didn’t mention it because I absolutely hate being a “parts changer”, but I changed both the float and the water inlet valve earlier this week, even after bench testing them.

FWIW, the OEM...

Yeah, I have the service manual and I am familiar with that section and how the upper/lower floats operate, along with the freeze timer, as well as the sequence of operation. I removed and bench...

5-Beeps - Freeze Timer WV off > 30 min. since last WV activation

This has been an intermittent issue where several days can go by with the machine pumping out ice. Then, it shuts down on the...

Yes, I did check which refrigerant and it was set for R-448A and the right stepper motor. All other parameters were set correctly.

I am happy to report that a new valve and stepper motor were...

The million dollar question.

Hopefully, they didn’t have it on the valve when they were brazing! 😬 But, you never know, right?

Thanks for the help!

The whole kit (valve body, stepper motor with wiring harness) on order next day air early AM. FYI, suction line temperature, suction pressure and resulting superheat were on point when the EEV was...

833365Yeah, it runs as long as the EEV is feeding the coil. Several times, the valve has stop feeding and causes the condensing unit to pump down and cycle off on low pressure.

Does this look...

Yeah, it’s the link in my first post. Thanks.

It’s a medium temp kitchen walk-in-cooler at an elementary school.

One 2-fan evaporator coil with EC motors.

Anyone have any experience with this setup? I am trying to diagnose whether or not I have a bad Electronic Expansion Valve (EEV) or an issue with the KE2 controller on this walk-in-cooler. I'm...

There is plenty of equipment in kitchens that aren’t on casters. Putting pieces of plastic cutting boards and tile under equipment for shims is for amateurs.

I’m assuming the refrigerated base is on casters? If so, change them out for adjustable legs. The griddle legs aren’t adjustable.

…or the equipment they sell?

I can vouch for that because we have one of the "simple" machines and, as long as it is cleaned, lubricated properly and worn out parts are replaced, it works like a champ.

I haven't been closely...

Yeah, I was in the middle of watching the Harris YouTube video, so I paused it and opened another tab to check out the threads/posts here to get some inside information from actual technicians. ...

They are for doors on a Thermo-Kool walk-in-cooler and walk-in-freezer.

They look just like this door.

I hear what you're saying. I don't disagree, but what good would it do to return them? These gaskets are manufacturer specific, made for specific doors and they have a specific part number. I...

I just got off the phone with Thermo-Kool. I was told that the ends aren't sealed because they sometimes need to be cut to length to match up with the door sweep. I understand that, but I've...

I ordered two Thermo-Kool 511500 Door Gaskets from Partstown for a cooler and freezer in one of my kitchens. The gaskets I received look just like the gasket in the photograph off of the Partstown...

Yes, the LPC is in series with the HPC and the Discharge Line Thermostat, but this system does not operate that way, if I am understanding you correctly.

Just to be safe, I called RDI technical support and they told me that Copeland requires that they install delay-on-break time-delays on their low temp condensing units with scroll compressors.
...

Great information on the “burping” issues. Based on that, I’m going to go ahead and install a new time delay.

Thanks!

I installed an RDI R-404A condensing unit during Thanksgiving week to replace an existing condensing unit. Other than a defective factory installed low pressure control on start-up, it has been...

Sorry for the confusion, but I was particularly interested in brazing with, what I've always called, "white rod". I've used it to braze steel many times, like Unistrut channel and simple things like...

Anyone ever do any oxygen/acetylene brazing on stainless steel using flux coated bronze brazing rod?

It's not a very clear photograph, but if you look closely near the end of the shaft, there are some cross-hatch cuts that are there to hold the wheel. I don't know if a sleeve would fit properly. ...

Yeah, I'm not particularly keen on hacking components for a gas appliance. Besides, I don't think I could get a drill bit on the hub at a 90 degree angle to drill pilot holes. Maybe Flex Seal? :LOL:

You would think that a manufacturer like Welbilt, who owns brands like Manitowoc, Cleveland, Delfield, Frymaster, Garland, Kolpak, Lincoln and Convotherm, among others, would do better at providing...

Okay, just to put a bow on this, I wanted to give a status update on my parts purchasing dilemma. It's pretty long, so hang in there.

Today, Heritage Parts is history. Even if you try to go to...

You're welcome. 👍🏻

Yeah, I hear you. When the health inspector is around, I'm usually as far away as possible. You definitely don't want to ruffle their feathers.

When I did restaurant work,...

That’s clear. Did you find the starting components?

Is this a residential beverage cooler? If so, don't you just throw those away and buy a new one? I mean by the time you do the leg work sourcing parts, pick up the parts, drive to the customer's...

I am the equipment service technician for a relatively small public school district. I take care of six kitchens - a high school, a junior high, three elementary schools and a kitchen for staff...

Unfortunately, that wasn't the case with the purchases we were charged tax. It's all been rectified, so I'm back to ordering parts from them.

That's funny you should mention that because I was...

Unforunately, AllPoints is not an option. I failed to mention that vendors we deal with have to be a member of Choice Partners purchasing cooperative because we're a school district. Thanks for the...

I don't know who you guys use for commercial kitchen parts, but I've been a Heritage fan for years. As you may know, Heritage and Parts Town have merged. I've never used Parts Town.

Supposedly,...

Update: I just wanted to follow up on this machine. I said I looked at the rack paddles and the actuator switches to see if they were aligned. Well, looks aren't everything. I forget which one,...

So, I've gone back over this thread and picked out things that I thought needed more detail. Admittedly, I kind of jumped in and didn't really pay close attention to what the issues were. So, here...

Y’all are forgetting the cam and its role in the operation of the control. The cam is engineered to work with a bi-metal with the properly rated voltage.

There you go! Look, I am not an engineer and I am not an infinite control expert, but this is what I think based on researching this issue after I read your post. Beforehand, I really couldn't tell...

He’s definitely a Guru. I’m trying to convince my buddy, who owns an HVAC/R company, to branch out into the hot side. He has a lot of restaurant customers. I did HVAC/R for decades before I got...

Yeah, I did use that to help explain. BTW, whatever happened to Ectofix (Earl)? He could probably explain things a lot better than I did.
