Ok.. Just a bit of info for you if you have to sometime in the future do a parts search. This unit is the same as the Hotpoint HSS25GFTWW
Now for the icemaker problem.
When ice makers start making less ice it is usually a sign of some other problem.
1. Ice build up on the evaporator coils in the back of the freezer.
2. A slow or not functioning evaporator fan.
3. Dirty condensor coils in the back or the unit
4. A condensor fan that is running slow or not turning.
5. An automatic defrosting problem (most common problem)
If you have ice cream you probably notice that it is softer than usual. Or things in the freezer just are not as stiff as they usually are. When you notice this the freezer is warming up but the fresh food compartment is fine.
1st.. check to make sure the control panel settings are set to "0" for the freezer and "37" for the fresh food compartment.
2nd.. look for any obvious signs of ling build up in the bottom and back of the unit.
3rd .. Listen to the evaporator fan in the freezer compartment.
a. must be running full speed
b. should not sound like it is striking anything
4th.. Is the chassis near the doors hot to the touch? (should be warm not hot)
a. if hot to the touch the condensor is not getting rid of the heat due to lint build up, or slow / stuck / failed condensor fan.
5th.. there is always the very rare chance that there is an actual problem in the ice maker. (thermostat)
