Solution
1. Inspect grid's heater wiring for
proper connections on AUX Power
PCB.
2. Remove system power, then remove
the fuse from the grid circuit. Check
fuse visually or with an ohmmeter.
3.Remove all lead wires from both
grid heater elements. Use an ohm
meter to measure resistance across
each element. Infinitely high resistance
values indicate an open heating element
and grid must be replaced.
