TROUBLE SHOOTING
B. TEMPERATURE CHECKS
1. Desired baking temperature is 390ºF ±5ºF (200ºC ±3ºC).
2. Turn the power switch ON and allow the Waffle Baker to heat for
a minimum of 30 minutes. Insert a pyrometer of known accuracy
betwen the grids and allow the readings to stabilize.
3. Temperature may be adjusted by removing the back panel,
and turning the dial on the temp controller:
CW to decrease temperature; CCW to increase temperature.
NOTE: Manufacturer’s calibration point (390ºF) is indicated by a black dot on the face of the dial.
A. ELECTRICAL TEST POINTS
B. AMPERAGE AND RESISTANCE CHECKS
1. Amperage may be checked with an inductive amperage tester (Amprobe™ or similar) by encircling
wire #4 at temperature controller terminal 2. Total amperage is 7.5 Amps with the waffle baker in
the pre-heat mode.
2. The heating element is integral with the Grid casting.
Disconnect wire #7 to #8 from temperature controller to check resistance of both grids at once.
Resistance from # 7 to #8 is 16Ω (cold) ± 1Ω. A reading of 32.0Ω indicates one defective element
or a broken element jumper wire.
Data for one element: 450 Watts, 3.8 Amps
Resistance of one element TP1 to TP2, (wires disconnected) is 32.0Ω (cold) ± 1Ω.
