
Inspect/replace wir-
ing between B-17,
C-14 of the control
board and terminals
A+B of the K2 relay.
Is voltage leaving the K2
anode relay on terminals
4+6?
Replace the K2 anode relay.
Are 10+ amps present
during the F3 fault
alarm?
Replace the
magnetron(s).
Inspect/replace wiring between terminal 4 (K2) and
T1-1 (HV transformer), and between terminal 6
(K2) and T2-3 (HV transformer; US 240 VAC) /
T2-2 (HV transformer; US 208 VAC or Intl.).
Energize the magnetron
circuit from Test Mode
(page 19) and test for
control voltage on the
K2 anode relay. Is 24
VDC present on
terminals A+B?
Confirm the F3 fuse is a
20-amp ATMR fuse. Is it
open/blown?
Replace the F3 fuse and
verify the operation of the
switches (page 35, section
“Interlock Switches”).

Run test cook
cycles to see if
fault repeats
(page 11). If
not, clear faults.
Did fault repeat?
NO

Energize the mag-
netron circuit from
Test Mode (page 19).
Are there 10+ amps
present on the cur-
rent transformer wire,
located on the control
board?

Energize the mag-
netron circuit
from Test Mode
(page 19) and test
for control voltage
to the K2 anode
relay. Is 24 VDC
present on pins
B-17 and C-14 on
the control board?
NO

Remove and inspect the
magnetrons for discolored
antennas or waveguide
contaminants. Were any
defects found?
NO

Test the filament transformers
(page 38). Are they functioning
properly?
NO
Test the capacitors (page 37).
Are they functioning properly?
NO
