Leakage; Basket Lift Malfunction - Frymaster FootPrint OCF30G Service & Parts Manual


The operator attempted to filter oil that was not heated. Cold oil is thicker and causes the pump
motor to work harder and overheat.
If the motor hums but the pump does not rotate, there is a blockage in the pump. Incorrectly sized or installed
paper will allow food particles and sediment to pass through the filter pan and into the pump. When sediment
enters the pump, the gears can bind up and cause the motor to overload, tripping the thermal overload.
Solidified shortening in the pump will also cause it to seize, with similar results.
A pump seized by debris or hard shortening can usually be freed by manually moving the gears with a
screwdriver or other instrument as illustrated on the following page. Make sure power to the pump motor
is off before trying this.
1. Disconnect power to the filter system.
2. Remove the input plumbing from the pump.
3. Use a screwdriver to manually turn the gears.

Turning the pump gears backwards will release a hard particle and allow its removal.

Turning the pump gears forward will push softer objects and solid shortening through the pump and
allow free movement of the gears.
Filter paper/pads that are installed incorrectly will also allow food particles and sediment to pass through and
clog the suction tube recess on the bottom of the filter pan or the suction tube, itself. Particles large enough to
block the suction tube recess or the suction tube may indicate that the crumb tray is not being used.

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
OCF30™ 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
