VHX SERIES STEAMER - ELECTRICAL OPERATION

Door Latch Adjustment

Should the cooker door jam and can not be opened, DO NOT FORCE OR PRY the door as damage will occur.

First, try lifting up on the bottom of the door at the handle end to disengage the latch. If that does not work, remove the right side panel.

The striker that catches on the door latch is located behind the front face of the cooking cavity. Remove the nut from the striker and this will release it from the panel.

Once the nut and washer have been removed, door will open freely.

Remove any burrs on the striker that may cause the latch to stick. Reinstall the striker and adjust, so door will not jam.

To adjust:

1.Reinstall the striker with the slot pointing upwards and hand tighten nut only.

2.Close the door to center the striker in the oval mounting hole.

3.Open the door and check the strikers’ slot for horizontal alignment. The slot on the striker must be kept horizontal in order for the door latch to catch it properly and latch.

4.Once the proper slot alignment has been set, hold the striker close to its base using a rag and vise grips, then tighten the striker nut. Be careful not to damage the striker slot when tightening or door may not latch properly.

NOTE: Do not over tighten as the striker will begin to turn and change alignment.
