High Temperature Limit Control - Henny Penny LVG-102 Technical Manual

7-4. HIGH TEMPERATURE
LIMIT CONTROL
June 2010
This is a safety, manual reset control, which senses the temper-
ature of the oil. If the oil temperature exceeds 425°F (218°C),
this switch opens and shuts off the heat to the vat and "E-10"
shows in the display. When the temperature of the oil drops
to a safe operation limit (15-20 minutes), manually reset the
control by pressing the red reset button.
The red reset button is located behind the doors, underneath the
controls; find the appropriate high limit and press the red reset
button; if high limit does not reset, high limit must be replaced;
If high limit resets, the oil starts heating.
Checkout:
Before replacing a high temperature limit control, check to see
that its circuit is closed.
Oil temperature must be below 380°F (193°C) to accurately
perform this check.
1. Remove electrical power supplied to the fryer.
To avoid electrical shock or property damage, move
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
2. Using a Phillip's-head screwdriver, or cordless drill, loosen
screw securing the top of control panel and secure control
panel in the slots of the shroud.
3. Open the front door, and using a 3/8" socket or nut-driver,
remove the 2 nuts securing the high limit bracket to the unit.
4. Pull high limit and bracket from inside of control panel and
remove the two screws securing the high limit to the bracket.
5. Pull high limit from bracket, pull back the cardboard
protector, and remove two electrical wires from high
limit control.
6. Manually reset control, then check for continuity between
the two terminals after resetting control. If circuit is open,
replace control, then continue with this procedure. (If
circuit is closed, high limit is not defective. Reconnect
the two electrical wires.)
