Reduced Ice Production

I have an Amana AFD2535FES bottom freezer refrigerator. Lately the rate of ice production has slowed. The cubes have their normal size and shape (crescent). I checked the freezer temperature and its right around zero Fahrenheit. This fridge has a bypass plug in the filter housing; we have a whole house water filter so I didnít see the need to install a filter cartridge in the fridge itself.

I read online that if reduced ice production is not due to water supply problems then the next most likely cause is a bad ice mold thermostat. Is there any easy way I can test the temperature at which this thermostat closes? It seems itís supposed to close at 17 degrees F. I also read these things usually fail catastrophically so the icemaker just stops making ice altogether.

Is there something else I should check? I can get the thermostat for about $8 on eBay. So if there arenít any other common failure modes I may just buy a new thermostat and replace it.

I rarely find a defective thermostat. Usually slow production is caused by the freezer not being cold enough or not enough cold air flow thru/around the icemaker itself.

It wouldn't hurt to change the harvest stat but I don't think you'll notice a major improvement.

Based on several temperature checks I believe our freezer is cold enough for ample ice production. It's right around zero F whenever I check it. Other than too much food stuffed in the freezer near the ice maker (not the case here) is there anything else that could cause not enough cold air flow thru/around the icemaker itself? Anything else to check?
