This is one of the in roof icemakers.
The original icemaker was bad. in test mode it would not harvest. Had an error code E2 when test 56 was run. No ice jam, so we replaced the icemaker.
tested the water valve just to be sure there was no problem with it and it worked fine.
Customer said it made ice once and then no longer made ice.
returned and found the fill tube heater not working and the fill tube frozen.. ok no problem. Maybe we damaged it putting the icemaker in. Put in a new fill tube heater.
Customer said same thing. It made ice once and never again. she can hear it cycle, but no fill or ice.
We go back again. fill tube is not frozen. no ice in icemaker.
Run icemaker test 56. no errors
run harvest test, all ok.
test valve, icemaker fills
customer calls later and says it made ice once and she can hear it cycling later, but no more ice and not water filling sound.
Reading the tech data, the water fill votage comes from board when the icemaker is done cycling. Do we have a bad board or a bad icemaker?
I ordered a new icemaker to install. just to rule that out. I use them fairly often so no big deal to have that in stock if it is not the solution. Don't want to buy the board unless I am sure thats the issue.
I have the tech sheets.. anyone seen this issue or have any thoughts?
