Sub Zero 590 I/M Whats UP..

8 posts in this topic

Greetings,

 

Replaces and I/M for 590 w/s# m1248207 first used a WP universal, seemed that the harness matched up but when I tested it no go allow 24 hours still no ice. I them replaced the IM with the proper SZ replacement as soon a it was plugged in to the harness, the I/M cycled and filled with water. I installed the I/m tried to jump t-h no go would not go through cycle. I assumed that the t-stat just needed to close, so I vfy 120V to L-N on the I/m all good, customer called back still not making ice.

 

1, is there an issues possibly with the harness?

 

2. when I jumped out t-h could I have shorted  the I/m/

 

3. I got voltage to the I/M is there a bin bucket switch that's going bad, seems to work fine but puzzled?

 

Any Sub guys run into this before?

 

 

Thanks,

 

Ken

Doesn't add up... does this icemaker require the door to be closed and if so, could you have been accidentally hitting the switch when you tested for voltage and when the second IM, which must have already been in harvest mode or somehow the bimetal was already closed, started harvesting?

If the above is possible, then you either have a faulty door switch or your freezer temps are off. But I will defer to any subzero experts. This is certainly perplexing to me as well.

Ice bucket switch has to be closed for IM to work. The switch is on the auger motor housing.

Find your water valve,......Up top near the compressors.........ALL  I/M switches closed.......Ice bucket,  System switch............. insert meter probes into the valve's  terminals / connector.............Run forced harvest on the I/M,.....voltage to the water valve at any time????......Fill tube blocked??????

Well I assume the fill valve is ok because upon the install of the new sz ice maker the call for water was herd and seen. the bail arm is the old one that I adjusted to fit so that it would not hit the screw to the right seemed the bail arm was sitting funny. I do belive that that was an old wp im bail arm. The Ice bucket switch seemed ok due to the auger called and working. I did not get voltage to the water alve from line to valve on the I/m, and t-h would not cycle when jumped out. I assumed the valve was ok and t-h was ok due to the ice maker advancing. Will look at ordering a new bucket swith and bail arm to start, however in the past a water valve was replace out with in the last year, and a WP valve was installed. When I check the valve for power I did not seem to get voltage, but when It called if filled.
