WARNING
Improper wiring installation Hot Wired to Neutral terminal.
Warranty is VOID.(SEE Installation Instructions.)
NOTE: Possible damage to glass.
1. Element is burned out.
2. Failed limit switch.
3. Failed infinite switch.
Failed infinite switch or limit has welded contacts.
Failed limit switch.
Loose or broken wiring.
Infinite switch or hot light switch failed:
NOTE: In case where light does not light, could be failed indicator
light. Possible inductance voltage, separate indicator light
wires running parallel with power supply wires.
Caused by a 60 Hz AC current passing through element winding.
Normal occurrence does not affect performance.
1. Failed infinite switch.
2. Improperly wired.
1. Knobs on surface controls indicating incorrect setting. (knob set
to HI control is actually set on LO.)
2. Improper wiring or switch installation.
Check for runaway surface control, faulty limit switch that could
have caused glass to break.
Manufacturing process gives glass − ceramic heater panel a slight
wave across surface.
This IS NOT a defect.
Glass−ceramic heater panels are slightly opaque. Element may
transfer a glow through a panel. This IS NOT a defect in the unit
and has no effect on performance.
1. See test procedures.
