I agree with jpsmith back in the 80s I had to clean the screens on those jolly greens so many times that I broke out with sores all over my hands and had to take steroids to try to stop it. Gloves...
I reread your post about the heater relay
Yes I have had these little black relays I think 90-340? the normally closed points fail as they only have a small spring pressure to close the points and...
Bad wire nut, loose screw on clock, spider or cockroach between those big 40 points on clock, LPC points or HPC lost deferential at certain pressures. I found sometimes 1/4" super hoses pass piston...
No sorry I sent it back to Ohio inside the warranty compressor 3 days old and the bit was the same size as the the holes for the reed valve pins so you know how it got on top of the piston before the...
Sounds like it may be replacement time. I didn't see a serial number. How old is it?
I'd try cleaning screens and a new pump
but it may be waisted time and $ if it's an old compressor
You may have...

I'm not a newbee but I'm still here to learn. Thanks to your post I never thought about it but there can't be less than zero...
That's what I was trying to impose on the original poster and how important correct SH is. We all were trained to set SH using TXV bulb temperatures not compressor suction temps
I seem to remember on Sporlan balance port valves on the superheat stem adjustment 1/4 turn had the same effect as 1 full turn on a G valve. This should be a warning to all mechanics don't use rules...
I think some mfgs state on the box that the valve is set with air pressure not the refrigerant number on the box if my memory is correct. If not please correct me. So seting SH is always best set by...
I went to a meeting once and had a sporland rep and alco standing side by side. I asked them why on the same system with two brand valves Why while adjusting SH one brand valve would change SH...

OK no reply on grounded wiring due to water condensation in the conduits
If it's not kicking the breaker
My next shot in the dark is
Overheating of the solenoid valve during welding on original...
Consider a possible vibrating ground in the condensor fan motor wiring or main wiring as far as that goes. If you have flex conduits, hit or move them around with a 2x4 to see if you get sparks or...
When I started in this field my mentors used Kotex to absorb acid which came from a breakdown of refrigerants made from acid which made for an embarrasing

Dumpster contents can also be a sad but yet funny surprise

Years ago I was setting SH on a two meat cases. One Alco and one Sporland
While adjusting one brand would raise/lower the suction pressure and the other

Talked to my KS lawyer he says liens are only good now in KS
for a period of one year and then it is gone with the wind

I'd say from the history tracks you're finding from the previous service work
done with the dimes under the power elements and other desparate changes
that have been made by other mechanics that...
Sound might be an answer

I agree grub worms are the problem here in Kansas

I see you're going to school would that be refrig school?
Some air compressor companies also own refrig companies
Yes your poor product condition may be a result of a head
Sorry about Christmas
I'm self employed (32 years) but
I'm in the same boat and that's why I really fear
the holiday seasons as they are worse as work always
bottoms out completely.
Where's the moisture coming from? and how many btu's latent?
From the product due to off gassing,outside air,washing operations,
vapor barrier failures in walls, ceiling or floor
Man is it slow here in Ks
