Henny Penny PFE-592 - Manual (Page 18)

Model 590/592
This high temperature control is a safety, manual reset control,
which senses the temperature of the shortening. If the shorten-
ing temperature exceeds 425°F (218°C), this switch opens
and shuts off the heat to the frypot. When the temperature of
the shortening drops to a safe operation limit, manually reset
by pressing the red reset button. The red reset button is located
under the control panel, in the front of the fryer, to the right of
the drain. Once reset, the frypot starts heating.

Before replacing a high temperature limit control, check to see
that its circuit is closed.
The shortening 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 the
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
2. Remove the control panel.
3. Remove the inner heat shield.
4. Remove two nuts securing the high limit bracket to unit,
and pull the bracket from the unit.
5. Remove two screws securing the high limit to the bracket,
and remove the high limit from the bracket.
6. Remove the two electrical wires from the high temperature
limit control.
7. Manually reset control, then check for continuity between
the two terminals after resetting the control. If circuit is
open, replace control, then continue with this procedure. (If
the circuit is closed, high limit is not defective. Reconnect
the two electrical wires.)
