Test Procedures
!
Before touching any oven components or wiring, always unplug the oven from its power source and discharge the
capacitor by shorting across the capacitor terminals with an insulated handle screwdriver.
Low Voltage (Controller) Transformer Test
An operational test can be performed to verify proper
operation of the low voltage transformer.
1. Disconnect power to the oven and remove the
control panel assembly.
2. With a voltmeter set to appropriate VAC scale,
perform the following test set-ups, measure and
record the voltage indicated on the meter.
!
WARNING
Do not touch any oven components or wiring during
oven operation.
TEST SET-UPS
Attach meter leads to wire harness
test points A - B, apply power to
oven and open oven door.
Disconnect power and remove L.V.
transformer connector attached to
the control circuit board and attach
meter leads into harness side of
connector at test points shown in
chart. Apply power to oven and
open oven door.

High voltages are present during the cook cycle.
Extreme caution should be observed at all times.
Procedure A: If the proper AC voltages were measured
as shown on the test chart, the low voltage transformer
operation is normal.
Procedure B: If abnormal reading was measured at test
points 2-4, 1-6, 5-6, as indicated on the test chart but
normal voltage was measured at test points A-B, replace
low voltage transformer. If no voltage was measured at
test points A-B, check wire connections and circuit
diagnosis for other possible causes.
NORMAL VOLTAGE (Approximate)
120 VAC on all models except
FS14.EVP.00, FS14EVP.A,
and FS14EVP.B which
is 208 - 230 VAC.
