Supco makes a universal potential relay for upto 5 hp. The way I understand it, is it's actually a solid state device that basically uses timing to open the contacts, not amperage.
When I did...
Check the pressure control settings. Then, check that the solenoid valve or compressor valves aren't leaking by.
Run the yellow plastic stuff. Make sure to run a tracer wire next to it. Buy the appropriate ends for it from your supplier you got the pipe from.
X2. I find it's easiest to put the manifold in a vise to get the valve out.
We stock 5/16 copper at the shop, just for tecumseh compressors. There are a lot of AEA4440YXA compressors out there.
True. But torching the reciever would tell you that too.
I do the same as ammoniadog does. I torch receivers on running systems often. Just make sure to stay away from the relief plug. Also, not to start the whole subcooling argument up again, but...
Make sure the dump valve doesn't have any debris in it, keeping it from closing all the way.
With all the parts/labor stuck into this thing, you could've bought a new one. Being a q, the plate is probably going out anyways.
The only way this day could've been worse is if your dog ran away, and your wife left you.
All kidding aside, every once and a while you get dealt a job from hell. I just had one myself, so...
Check gas pressure and draft.
Found the problem after talking with tech support. There are two solenoid actuated damper plates that are used to save heat when the burner isn't running.
The linkage rods had broke off the...
Make sure honeycombs are clean, and all fans work.
I'm working on a Southbend oven. Model: GS/15SC Serial:16E40781. This oven is stacked above an older southbend, flues tied together. The lower oven has no issues, and performs flawlessly. The...
Try the universal dixell control, I think it's an xr60. Comes with controller, and sensors.
The sporlan szp mop powerhead has a max pressure of around 35 psi. I see this used frequently in norlake walk in freezers.
How did you disable the probe? Does the machine go into harvest after the 6 minute minimum freeze cycle?
Were you also checking the voltage at the unit while measuring amps? And yes, I have had loose breaker connections cause high amps.
If there is no sight glass, just torch the reciever. Checking subcool on a reciever system is kinda pointless for the most part.
Sounds like you need a harvest assist assembly. That includes the motor and cam switch. Usually if the top relay burns up, I've found the cam switch is going out.
You need to put a gauge on to see...
Front seal on tk is a gravy job, atleast it was on the sb units.
We need more info
The outer bearing race on the bottom bearing always rusts in place. Since its inside the housing and recessed, I found that welding a washer on it and tapping or pressing it out works.
Replace all...
Nice write up TB
SLC tech has a great youtube video about them.
We have a few places with those yet. Get all of the times set correctly. One dial is defrost frequency, the other is duration. As someone said, pushing the black flipper initiates a defrost.
Look up sporlan bulletin 90-30-1
The evap coil(s) in the lower refrigerator is what I have found.
Thanks for the info. I will be reading through it all. Most ovens I service are convection, so the bypass flame is new to me.
That is correct. The 700 feeds the FDTH valve. Thanks for the info
I replaced a temp control valve on a bakers pride pizza oven. The main valve is a bobshaw 700, which feeds to an inversys temp control valve.
After it was installed I found the flame stays on...
If the cabinet is in good shape, I'd replace the evap.
My van is similar to supa. I have plexiglass over the holes on my divider. The whole divider is carpeted, as well as the shelves.
The cab is quiet, and heats and cools quickly.
If you think the fan isn't spinning fast enough, this could cause freeze ups. Otherwise there should be a constant cut in control for defrost. Make sure the door closes, and the door gaskets are in...
My fire department gets them through a fire and safety equipment vendor. The good ones are quite expensive, and need to be tested weekly as well as being recertified annually. There are several...
What he was referring to was a four gas meter. They display 02, CO, and H2S levels, as well as LEL, or lower explosive level.

Do a YouTube search for carrier clo board. Slc tech has a great video on them.
Ditto. These thermistors are notorious for going bad. I have changed quite a few. It would be an easy repair for you to do. The kit comes with a universal thermistor, and stickers to label it,...
Why did you replace the compressor to begin with? With low pressures, I would be determining if it is low on charge, or has a plugged cap tube.
We drill a hole in the bottom, and drain the oil into a barrel. The barrel gets sent to a local auto shop. We then take the drilled compressors to the scrap yard.
We take motors as well, but we...
I have a ridgid offset flaring tool, very happy with it.
Some of the sporlan LAC valves are dual pressure rated. They will be 180psi with the dome charge, and 100 without. You will notice the 180 and 100 stamped into the valve body of the valve. You are...
I hope you added fuses to the secondary side to protect the new transformers you installed.
As long as he keeps his nitro pressure below the high side pressure, he should be fine.
If it has a headmaster, follow sporlan 90-30-1 to charge. Subcooling is irrelevant with a reciever. Torch the reciever to see how full it is.
Don't worry about subcooling if the unit has a reciever. Search "subcooling and recievers", there's a ton of great info in previous threads. I also recommend the Dick Wirz book, and looking through...

I bought one of these from the local supply house.
