REMEDY
Thaw food prior to placing in oven.
Test air sensor by placing sensor in ice
water bath and using an ohmmeter set on
the ohm scale. The reading should be
approximately 100 ohms resistance. If the
sensor tests out and there are bullet connec-
tors on the leads, cut off bullet connectors,
strip back the insulation 1/2", slide a piece
of heat shrink tubing over the wire, twist the
wires together and solder. Slide the heat
shrink tubing over the soldered connection
and heat in order to shrink material.
Change the voltage setting, referring to the
instructions in Section 6, Service Setup.
Replace heating cable.
Test air sensor using remedy instructions
above for 1B.
Replace solid state relay.
Test food probe by placing in ice water bath
and using an ohmmeter set on the ohm
scale. The reading should be approximate-
ly 100 ohms resistance. If the product
probe tests out and there are bullet connec-
tors on the leads, cut off bullet connectors,
strip back the insulation 1/2", slide a piece
of heat shrink tubing over the wire, twist the
wires together and solder. Slide the heat
shrink tubing over the soldered connection
and heat in order to shrink material.
Close door.
Replace door gasket, adjust door placement,
or replace door.
Return to power-up preheat mode.
Change the voltage setting, referring to the
instructions in Section 6, Service Setup.
Test air sensor using remedy instructions
above for 1B. Test product probe using
remedy instructions above for 3A.
Replace solid state relay.
Check wire connections.
Replace heating cable.
Replace solid state relay.
Test air sensor using remedy instructions
above for 1B.
Replace heating cable.
