Manitowoc QY0214A trouble

[char24]

Hey guys I am new at this forum so please forgive me if I am posting this in the wrong area.
I have had my QY0214A under counter ice machine for about 5 years now. I bought it used. For the first few years it worked fine but these past 2 years the machine turns off during hot weather.
When I come to open the business the following day the ice is already melted and I have to hit the reset button and then it works again. Ice productions is a slow and I will never have more than a quarter of the bin full on any day. In the winter time, the machine seems to function properly. Please advise. Thank you.

Make sure the mesh filter behind the machine has been cleaned. Take it off and flush the filter with water.

The filter was cleaned and the area is not that well ventilated. Thanks for the reply.

If the filter is clean ventilation may be the issue, what temperature is the ambient it's in?
