The neither the high or low pressure changes when the compressor is running. Are they supposed to?

Thanks

if it pulls in a deep vacuum with compressor running it's restricted 20 in of vacuum would be like no freon and the pressure would rise as freon was added if it goes back in a vacuum something is plugged

If the bin thermister was disconected so it wouldn't run, how did you charge it with half a can, and if you don't have the hoses to do the job, just curious.

Good question, long story. I can actually add freon, just not through my guages.

I added an automotive 134a snap connector to the low side and connect the guages using this:

Then I have to remove the guages and connect a can like this:

I added the rest of my can of freon (maybe 1/4 of a can).

Low was -20 now -17
High was 94 now 240

Condensor is cool.

This probably isn't a good idea, i did it accidently. If I let the freon go from the low to the high through the hoses the condesor will get hot.

Any ideas?

Thanks

Based on the low side pressure, looks like your heading in the right direction. It is hard to tell how much 134 your adding without measuring it. How much does the icemachine call for? It's listed on the model# tag

Reach underneath the evap and feel the accumulator, is it colder than room temp?

It calls for 6.5 oz by weight - added through the high side. Based on everybody's feedback about the low side vacuum it seems as if there's a clog. I was going to remove the evaporator and see if I can find a clog.

This is what the tag says:

The inside of the icemaker door has a label that says:

Design Pressure
95 PSI Low
350 PSI High

Should I add more freon?

No it's not cooling at all. It's room/tap water temperature.
