It was the compressor. Readings were way to close. The relay was bad which is probably what did in the compressor. New compressor and drier all is working well.

According to Tecumseh spec sheet RLA 4 amps, LRA 31.
Start relay was found to be bad, all start components were replaced including run cap.
C-S = 2.3
C-R = 1.9
R-S = 4.1

Walk in cooler, Tecumseh compressor AKA9442EXD, R-22.

Customer calls walk in cooler warm compressor hot. I check unit and find the potential relay contacts not opening and further inspection find...

Have not had the water tested, but we have very hard water here in Florida.
The ice machine gets a lot of scale build up. I have been looking at filters, some are one cartridge and say they can...

I'd like to get an idea of what water filter most of you are using for ice machines.
Some of these filtering systems are quite pricey.
I am currently looking into installing one on a Hoshi...

Thanks 24, I appreciate the input.

I have a Scotsman Flaker, M# AFE400A-1B, S# 0407132 0016338, that I have to replace the gear motor bearing on. I have not worked on one of these yet so I was looking for a heads up on what I may...

Thanks for all the replies. I'm going to replace the cap tube again and use the 032 drier instead of the copper one. Hopefully this will last for several years. I hope.

Cap tubes and POE just not a good mix. I'm going to have to fix this again, I just hope it's not every seven months.
I wonder if I'm better off putting a regular filter drier in rather then the...

Seven months ago had a TDD-4 keg cooler with cap tube restriction. Opened system, blew out with nitrogen, changed compressor oil, factory cap tube (.046 x 10') and factory filter drier, vacuumed down...

It is wired correctly. What is the best temp setting for defrost termination?
Is 50 degrees about right?

You did get it right. Thank you.
1- possibility, the defrost is set for twice a day every twelve hours. I told the owner I was going to put another one or two defrosts in there. Do I need 4?...

First let me say thank you to all of you that shared your knowledge and experience in helping me out with this freezer. This was a great learning experience. Things are looking much better.
When I...

A damaged reed would cause the high suction pressure I'm seeing?

To many hands in this thing previously. Have to check the obvious first. If it were running on one cylinder would I still pull 5.6 amps?
Don't want to change a pump and then find out I have a TXV...

Today 21 degrees and hopefully still dropping.





No I did not test it this way. I will do it tomorrow. Just to make sure i do it right this time. Run unit, jump LPC, close suction valve,...

When I pumped it down the pressure climbed to 8 and held there so I figured it was just some residual refrigerant. I did not pump into a deep vacuum, shut it off as soon as it hit zero. I'm leaning...

I spoke with the owner and apparently he had a few guys out there before me. The last guy he said was there for 15 minutes and said he added refrigerant. I looked the system over again and checked...

Thanks for the replies. I'm downloading the performance calculator as I type.

Powell out of your four options I like number four. I'll bring an extra large hammer.

It has a receiver. Your suggesting from the pressures that the valves may be damaged and the refrigerant is bypassing? Best way to prove this out I guess would be powell's suggestion of a pumpdown....

Box is small , 6 x 6 or 6 x 8. Box is in good shape, Its fiber glass inside and out. I did not get the amp draw I will get that tomorrow. Condensing unit is on roof of box and no disconnect so hard...

My thoughts today exactly.

Now Now calm down. Some of your questions are answered in my first post. As far as the site glass goes I am not concentrating on it, I made a comment about it so I could get some constructive...

My initial thought was that I am still low on refrigerant and that my high side was a little low and my low side a little high. I figured the low side was high because of the box temp.
If a freezer...

Had a call for a walk in freezer not dropping below 30 degrees. Last call late this afternoon so not much time to hang around and watch the unit. I will be returning tomorrow to spend more time on...

I got a headache just looking at this monster.

Not much of a refer guy. But my first question would be depending on how thick the ice on the suction line is, are you actually taking the temp of the line or of the ice build up? The saturation temp...

So how did this work out?
Did the larger return help your problem and increase air flow? You should have noticed a considerable amount of increased air flow out of your supply registers.

If you only have the one return mentioned and it truly has only an 8 inch duct attached to it, that is a big problem, the return is way undersized.
Upon initial start up, this small of a return...

Supposedly it is the same, but I am not sure. I am going to try one to see if it is the real thing.

I live in Florida also. My homeowners insurance has risen a total of 500 percent in the last two years. The insurance companies have gone crazy. People are trying to move out of the state but the...

The builder mentioned a dirty filter. But did he change it? Depending on how bad the filter is could have a great impact on the cooling capacity of the system. If not enough air passing through the...

I would do as Yota suggested pull the charge, evacuate and weigh in the proper amount of refrigerant per the dataplate. The last table I did only held 9 Oz of refrigerant.
Also unplug the compressor...

I believe that is a 10 Seer unit. But I would wait til one of the trane guys respond to be sure.

I'll have to agree here. I'm sure there was some sort of return through the ceiling at one time and through the years they were covered up.

At least they left a vacuum and a broom down there so you could tidy up before you left.
Remember a good tech always leaves the place looking better then when they arrived..

Anyone know where to get parts for Ice-O-matic ice machines. I am in the Tampa Bay area, Florida. No one in this area seems to carry the line that I can find.
I just sent an e-mail to Ice-O-matic to...

43 here. Florida West Coast. Actually had to put the heat on.
Stay warm.

This tester is the best for testing the lights. It actually works. I have been using it now for several years and it sure has saved a lot of time, no more pulling one bulb at a time to see which one...

I'll tell. For a dummy, Ice's posts sure make a lot of sense.
How he does it, I don't know. Could be the eighth wonder of the world.

Thanks for the replies.
My main concern was component match up since it looked like the TXV was replaced at one time. Ice and the Fridge confirmed that the match up is correct.

I am working on a walk in cooler that has a restriction in the drier but I want to make sure the components in the system match up correctly since I have to open it up. The expansion valve looks like...

To install ductwork and to do it properly so there are no leaks for many years to come is a highly labor intensive job. You can have it done quickly for less money, but if you want it done correctly...

I do not work outside in the rain. I have this phobia when it comes to water and electricity. Besides who knows what has been done to a unit from a previous service company.

Owner did not think the machine was working properly since there was no ice after a busy weekend, plus the fact that they emptied the remaining ice for a Sunday fishing trip.
After cleaning the...

The ice looks good it is very clear.

Looking for some advice on the following.
Friend owns a bar and he does not think his ice machine (Hoshizaki KM-1300SAF) was working properly and asked me to look at it. It was a 93* day and the...

Check that coil to see if any thing was sucked up in it and blocking it. TD of 30* points to low air flow. Need more info from you to get a better idea of what is going on with the system. Pressure...

Stamped registers usually have less free space (to much restriction), the louvered ones will open up the register more.
Some of the stamped I have seen in place run the air to much to the ceiling...
