Replacing the Temperature Probe

1. Drain the cooking oil to the filter pan using the controller "drain to pan function".
2. Disconnect the fryer from the electrical supply or remove fuse on bottom of
associated control box.
3. Reposition the fryer to gain access to the rear of the fryer.
4. Remove the four screws from both sides of the lower back panel. Then remove the
two screws on both the left and right sides of the back of the tilt housing. Lift the
tilt housing straight up to remove from the fryer.
5. Locate the red, black or yellow and white wires of the temperature probe to be replaced.
Note where the leads are connected prior to removing them from the connector. Unplug
the 12-pin connector C-6 and using a pin-pusher push the pins of the temperature probe
out of the connector.
6. Remove the securing probe bracket and metal tie wraps that secure the probe to the
element (see Figures 4 and 5). Remove the ground clip on the probe shield.
7. Gently pull on the temperature probe and grommet, pulling the wires up the rear of the
fryer and through the element tube assembly.
8. Insert the replacement temperature probe (wires first) into the tube assembly ensuring
that the grommet is in place. Secure the probe to the elements using the bracket which
was removed in Step 6 and the metal tie wraps which were included in the replacement
kit.
9. Route the probe wires out of the tube assembly following the
element wires down the back of the fryer through the Heyco

Controller Malfunctions

RECOVERY TIME
Recovery time – is a method of measuring a fryer's performance. Put simply, it is
the time required for the fryer to increase the oil temperature from 250ºF to
300ºF (121ºC to 149ºC). This range is used as a standard since ambient kitchen
temperatures can affect the test if lower ranges are used.
The M4000 controller performs the recovery test each time the fryer warms up.
An operator can view the results of the test any time the fryer is above the 300ºF
(149ºC) point by pressing the
