Arrived at location on 4/4/23 - Examination of the unit. Found the door handle in the lock position causing the handle not to close properly. The customer does not have a key and a piece of the lock is broken. Put oil in the fryer and let heat fryer hold temp at 360. Will order a new door handle per Trish and call the customer when the part comes in so they could open the door. Returned to location on 4/13/23 - Removed and replaced door latch kit. Unit tested good.
