Issue
Broken tray as a result of arcing at front lip of cavity.
Warranty
Ceramic trays may be claimed under warranty only if damage was caused by
antenna failure (arcing).
Trays are not covered under warranty if there is evidence that damage was caused by impact,
thermal shock (frozen or refrigerated product placed on warm tray), oven operated with metal pans,
oven operated without a food load or lack of proper cleaning and maintenance.
NOTE:
Typical symptoms of metal pan usage or empty cavity operation include arc spots on the
front lip of cavity, 1 to 2 inches from either side.
Action
If encountering arcing at front lip of cavity, proceed as follows:
1. Check antenna operation – if either antenna is stalled, hot spots will occur.
2. Remove oven tray.
3. Thoroughly remove any carbon build-up from front lip using fine grade sandpaper.
4. Thoroughly clean cavity and front lip removing all old RTV.
5. Before installing new tray, apply a generous bead of RTV on the front lip of cavity, (see below).
6. Install new tray and reseal using instructions supplied with the tray.
7. If arcing has damaged the oven door, replace inner oven door and inspect door ring weldment
for arcing.*
8. Replace door ring weldment if it is damaged.*
*
To ensure proper operation, use the instructions in the Service Manual when reinstalling the
oven door.
Apply a generous bead
of RTV along this lip
before installing oven tray
