Leakage; Basket Lift Malfunctions - Frymaster FOOTPRINT 8196345 Service & Parts Manual

1.10.6 Leakage

Leakage of the frypot will usually be due to improperly sealed high-limit thermostats, RTD's,
temperature probes, and drain fittings. When installed or replaced, each of these components must
®
be sealed with Loctite PST56765 sealant or equivalent to prevent leakage. In very rare cases, a
leak may develop along one of the welded edges of the frypot. When this occurs, the frypot must be
replaced.
If the sides or ends of the frypot are coated with oil, the
most likely cause is spillage over the top of the frypot
rather than leakage.
The clamps on the rubber boots that hold the drain tube
sections together may loosen over time as the tubes
expand and contract with heating and cooling during use.
Also, the boot itself may be damaged. If the section of
drain tube connected to the drain valve is removed for
any reason, ensure that its rubber and clamps are in good
condition and properly fitted around the drain tube when
it is reinstalled. Also, check to ensure that the drain tube
runs downward from the drain along its whole length and
has no low points where oil may accumulate.

1.10.7 Basket Lift Malfunctions

Protector series gas fryers may be optionally equipped

with automatic basket lifts to ensure uniform cooking

times. Basket lifts will always come in pairs, although
each operates independently of the other. A modular
basket lift consists of a toothed rod to which the basket lift arm is attached, a reversible-drive gear
motor, and a pair of roller-activated microswitches. A gear on the motor shaft engages teeth in the
rod. Depending upon the direction of motor rotation, the gear drives the rod up or down.
Timing circuitry in the controller initiates and stops operation of the basket lift depending upon the
variables programmed by the operator. When a product button is pressed, the timing circuitry
activates a coil to supply power to the motor, which lowers the basket into the frypot.
When the rod contacts and closes the lower microswitch, power to the motor is cut and the direction
of current flow is reversed; this reverses the direction of motor rotation. When the programmed
cooking time has elapsed, power is again supplied to the motor. The motor raises the basket from
the frypot until the rod loses contact with the upper microswitch, cutting power to the motor and
again reversing the direction of current flow.
Problems with the basket lift can be grouped into three categories:
• Binds and jams
• Motors and gears
• Electronics.
