The Product Probe does not Work
Check the condition of the product probe and product
probe wiring. Is there any damage, kinks, or cuts to
the wiring, damage to the probe sensing tip, or
damage to the female connecting port of the probe?
No
Utilize an undamaged probe and go
to the next step.
Yes
Check the condition of the product probe receptacle
and clean the prongs. Re-attach the probe. Does the
probe read temperature now?
No
Dirty receptacle.
Yes
Measure the resistance of the product probe with the
probe inserted in a cup of ice water (approximately
32°F). Does the probe read 100Ω ± 2Ω?
No
Faulty product probe. Discard and
utilize a new product probe. Retest.
If probe has the correct resistance,
but the probe temperature is still
not coming up, continue with next
step.
Yes
With product probe in a cup of ice water and attached
to the probe receptacle, measure the resistance of
the wires coming from the probe receptacle to the
control board at the J4/J6 connectors. Is the resistance
still 100Ω ± 2Ω?
No
Remake wired connection to the
plug on the control board. If
resistance still does not fall within
the 100Ω ± 2Ω tolerance, replace the
probe receptacle and retest.
Yes
Is the oven configured to look for the correct number
of probe receptacles?
No
Correct the probe receptacle
configuration in the oven set-up
menu and retest. If no product
probe temperature shown, continue
to next step.
Yes
If the oven has more than 1 receptacle, swap wires at
the control board from a product probe receptacle
that is working (receptacle X) with the product probe
receptacle that is not working (receptacle Y). Does
receptacle Y continue to not read product probe
temperature correctly or is receptacle X now reading
incorrectly?
No
Control board faulty. Replace and
retest.
Yes
Restore the wiring to original state and retest. Is
receptacle Y reading correctly now?
No
Faulty wiring connection.
Yes
Replace product probe receptacle and retest.
