Maytag Built-in Refrigeration Manual page 62

Move the copper inlet from the primary valves to the secondary valves. This valve
assembly will directly feed the icemaker and the dispenser with a minimum of tubing.
Even with the filter eliminated from the water flow, the bypass cap must be in place to
allow the water valves to energize.
As with all dispenser systems, if you experience frosting in the dispenser chute, it is an
indication of air infiltration around the fountain door (chute flapper). Check for burs or
flashing around all components and gently remove if present. To help locate air leaks,
shine a flashlight down the chute and look for light leaks around the exterior of the
fountain door.
