I realized this after I posted. Dunno what I was thinking. Really seems like something intermittent is happening every couple weeks that I just cant see. This is going to be a major PITA.

Right on the compressor terminals.

Inside the walk-in about 15ft of piping from the condensing unit.

Ok I was able to come back today. Voltages measuring across all 3 legs is 208, 208, and 209. Current outside air temp is 72 degrees. DLT measured approx 10 inches from compressor outlet is 146. Box...

Have a customer with 2 identical Turbo Air 7.5HP R404a units. Each are piped to two blowers. About a year or so ago I kept getting calls from the customer for one side of the box is about 10 degrees...

I think your being a little extreme with this. Obviously I know this is not good practice and should be avoided at all costs... I was just merely trying to give some input on what will work and what...

+1 to this. I would never sell any of my customers any of those self contained shit boxes. Call a refrigeration contractor and order a real walk-in. All of those self contained ones seem to be...

Coil cleaner and blast out with nitrogen. It does make a mess but it's not your problem. Explain to the customer it NEEDS to be blown out and for them to put away or cover any product they have out...

The fact that this thing is even satisfying and cycling on the thermostat shows that not only is it working, but it's working well. Make sure your not checking temps while the box is empty like the...

I agree... condemn the system and the box if your able. It's old enough where the customer should understand it just needs to be replaced. It's most likely just no longer efficient.

I've been using R422b. (NU22) The best thing about r422b is that it is compatible with any oil. The pressures are very close to R22 but obviously you should use the P/T chart that is printed on the...

+1 to this. I've put a hard start on one and changed a t-stat on another. They dont seem terrible and they aren't too bad to work on. True is nothing special anymore. I actually hate the new True...

How is this even possible though? Why isn't the breaker tripping? Your clearly have a direct short to ground?

Copper spun drivers are garbage. Almost all will eventually plug up. When I have a suspected cap tube plugged, I change the driver and usually cut away about 4 -6 inches of the cap tube. Usually this...

And +1 to the everpure setup. That's what I install when a customer requests a filtration setup.

Not changing the filter ever will eventually lead to the filter plugging up which will restrict or totally eliminate water feed to the ice machine. Can't make ice without water!

If the condensing unit is below the evaporator then no, no oil trap is needed. If it goes up a few feet before it goes down then it's up to you, but I usually only install traps when it goes up 6 or...

unless the last tech that put it together was a dumbass and brazed it with regular 15% you can just flux the joint and re solder it with the right stuff because thats probably whats on there now....

cant use regular 15% brazing rod it will be almost impossible and most defintely leak even if you think your temporarily successful. Need to use safety-silv 45% as others have mentioned its almost...

like to do a single cleaning? some of them hardly need a cleaning and im just pretending to wipe and scrub to justify the rental bill. Other places like subway where they bake their own bread im...

have about 30 i rent. i dont have them insured. doesnt sound like a bad idea but it may cost more than its worth.. have never had a problem with a fire or vandalism but i put in the rental agreement...

an old r12 reach in freezer with a bad comp and clogged tube.. why the hell didnt you just sell him a new freezer!?!?

and no there is no way to increase harvest cycle length.

what is the bridge thickness of the ice? as one poster already said, increasing the ice thickness a bit will help it drop easier. Also some of the larger manitowocs have 2 hot gas defrost valves....

Well all i did was remove the charge, vac it out and charge it with virgin refrigerant. And it worked fine!? I called tech support (hill phoenix) and the guy there seemed to think headmaster may have...

What do you mean micro channel condenser? Its a 1.5 hp trenton low temp condensing unit outside

Small dot shop near called me about their 2 door ice cream freezer.. unit has an outdoor trenton unit cycling off on high pressure. Compressor only runs a fraction of a second before it shuts down on...

This is how it should be in my opinion. Its how it used to be. Whats the need to get all fancy now???

Ok guys, what i wanted to do was raise the default limit temp of 220 to like 260 but there is no way to change this in the advanced settings. The only thing i could do was put it on a constant...

So what would you do?

Change the condenser fan motor first and see if the problem still happens?

I dont see what could possibly cause it to trip other than a dirty condenser. Condenser is spotless.

Thank you i actually found that document last night searching about this. Not sure why i am getting it though.. when i went the first time i cleaned the condenser and blew it out with nitrogen. Its...

I didnt measure the temp of the discharge line i will do this when i go tommorow.

Hey guys last summer I installed a new copeland low temp condensing unit for a customers walk-in. I had a call that it was down. The unit has one of those new style emerson display controllers that...

150degrees for 409A is about 300psi. Make sure your high pressure cutout is set for 300 not 150!

Set your water regulating valve so your head pressure maintains about 150 for 409a. Doing it by...

Ok thanks everyone for the response

Need a little more insight on how you charge with this expiramental method. Lets say for a reach in the dataplate says 10oz 134a... so you put in 2 oz 134a and then 8 oz 404a? Or are you doing 2 oZ...

This looks incredibely helpful but what do i input for the original id? And the new id would be BC2?

What do you mean adding 404 on a 134a system? Can you explain this?

There was easy access to the cap tube into the evap so it really wasnt a hard replacment.. i also had a helper.. why do you guys seem to think my cap tube is to long. Are the supco charts that the...

What the others said is true about over use of full strength and non acceptable cleaners.. but for as much as an ice o matic fan that i am.. their evaporators sometimes just suck. Ive replaced many...

POS beverage air 2 glass door bar back cooler for wine and beer. Arrived to find dirty condenser. Cleaned it GOOD and put my low side on. Suction is in a vacuum. I throw in some 134a and get it up to...

I understand the refrigeration aspect of it. The two ive worked on were both 134a. What about glycol and water percentages? Ive heard alot of times these break because the gycol and water can leak....

I'm starting to get into servicing some glycol beer line systems. Ive had customers for a while calling me to fix them but ive been turning them down for a while because ive never worked on any. Have...

Yeah id just be nervous about killing the evaporator. I was able to get the iron stuff off by running about 5 clean cycles with the manitowoc cleaner and hitting the evap with a toothbrush. Evap...

Yeah thats the info i was looking for. I dont think i want to risk it then. I think ill try the squirt bottle and electric toothbrush someone above mentioned.

This is a manitowoc machine. I feel like if it had the harvest assist like the ice o matic does this wouldnt even be a problem. Didnt want to put an IOM here though because the left side is basically...

Plating is not destroyed when the cleaner is running over it you can actually see the nikel plating shine. Machine is not even a year old yet.

Can i use this stuff on an ice machines? I saw a thread in the past where it was being discussed. I have a customer with a 22 inch manitowoc that gets supplied with well water pumped from the pits of...

This is why circuit boards and electronic sensors should not be in ice machines! Ice-o-matic all the way. Ive never even seen one of these machines. Where im at its all IOM Manitowoc and the...
