I have some info on that machine. Manatowik model EY0404A serial 900761118 compressor is RRS40075. New number for that comp. is RRT10KIEPFA959 POE oil 134a the old comp was r12. I don't like the idea of a 134a ice machine cause I've never seen one. Also copland has RRS40075 listed as HT? How is this possible? I'm going to suggest replacement of entire machine the RSN40050 I was giving them has about half the capacity of whats needed so wont work

Yeah, it would stay sky high, regardless of overcharge, unless it were so overcharged that you were pumping liquid through the compressor, and if that were the case, the compressor is trash anyway.

The fact that it took over an hour to harvest ice in the first place is a part and parcel of a lame compressor.

Also, if you were bypassing hot gas, there would not be a limit on the discharge pressure. It too would be sky high.

too sophisticated to have any of that stuff, will get back to you though. Im just guessing 3000 btu/h is a little less capacity than this machine might require.

HaHa... Sorry you only get one wish I take it you don't have the ice machine model # or a flashlight ?

damn your good, just checked by candle light rsn4 0050 think it'll work?, just use your telepathy to know whats in the machine now okay?

No Copeland rsa's but if that's say a RSN4-0050-IAA it would be 4,380 btu/hr @ 20/120 or 2,900 btu/hr @ 0/110

Do you have the specs on both compressors so we can compare ?

if the chiller weren't in my yard for ten years and I knew a bar that needed it but given the circumstances ill cannabalize it. its old n after Ill still have the condenser coil and some scrap steel. $25 is really cheap for a comp. but its seen some service an I ain't gonna guarantee is longevity but im sure it'll pump better than whats in there. Plus I make my money on the profesional transplant.

Dont want a misdiagnosis either..... im gonna check n recheck then its heart transplant. I knew I saved that thing for something.

That glycol chiller is worth much more then that. You should sell that to the local bar.

That sounds great. Be sure to let us know the results.

I have never seen a R12 ice machine many 502's though.

I forgot to mention this machine its in its twenties. A while back I adjusted the sensor to compensate for ice bridge thickness variation due to temperature glide in evap with 414b its an old r12 and some other charged it with hotshot, maybe when that oil showed up. Its not freezing the evap. If there would be no harvest with a leaky valve then Im still thinking comp. cause it does harvest just takes forever.

If you were

Bypassing hot gas, the superheat would be sky high.

You have a weak compressor.

well saw that oil before when it had a faulty spdt power switch. I haven't seen many leaks without the telltale oil so we think alike icemeister but its plenty charged superheat is dangerous low. So if it has a harvest but just takes forever then weak comp. if it never harvests then leaking valve, I'd love to hear its that simple especially cause I already said it was ineffiecient comp.

If valve were leaking would there be any harvest?

No. If bypass leaking, there will be no harvest because there will be no ice. No ice = ice sensor probe not shorted to initiate harvest (or whatever type you have). Do you remember what type/brand machine it was?

That would be a full time harvest. There would be no ice to harvest.
