Arrived on site to check Pitco Fryer filter system. checked and found left fryer not actuating filter pump motor when pulling return filter lever. found reed switch behind left fryer drain valve hanging down on one side. screw missing to mount reed switch to mounting bracket. straightened reed switch and tightened existing screw. installed heavy gauge wire in 2nd hole to keep switch from swinging down again. filter pump is now operating for left fryer. filter pan is completely filled with oil, customers responsibility to clean pan out. both fryers operating filter pump. filter system back in operation.
