What causes a PLC Alert MTR Reset
When the auger moves Ice forward during a vend , Ice has to have a place to fall. If a bag or other object covers the Ice fall opening Ice will then compress to the front of the Drop shoot. Once compressed it will have to be removed or wait until it melts out.
Bags that fail to open or bunched up are a common culprit. Check the bagging area for obstruction.
Lift Handle magnets being always on on older HD machines will also cause this to occur.
