1-341.10.5 Troubleshooting the Temperature Probe

While it is still in the frypot,

inspect the probe body for

damage. Inspect the leads

for fraying, burning, breaks,

and/or kinks. If probe is

bent, dented, or cracked, or

if the leads are damaged,

replace the probe.

Determine the temperature of

cooking oil/shortening using a

thermometer or pyrometer

placed at the tip of the probe.

Disconnect the 15-pin harness

from the controller. Measure

probe resistance using J2

Pins 13 and 14.

Is resistance

approximately equal to that

given in the probe resistance chart

for the corresponding

temperature?

Measure resistance

through J2 Pin 13

and ground and J2

Pin 14 and ground.

Is resistance of

each pin 5 megaohms

or greater.

Yes

Probe has failed.

Probe is OK.

Yes
