1. Check the incoming voltage to the unit. There should be 240 volts with a neutral.
2. Program the unit into pure convection. Check power at the Dbl (double line relay) from
(Com) to neutral. There should be 120 volts incoming to the Dbl. Refer to picture for
test points. If voltage is ok, move to step 3.
3. Check voltage across the DBL (double line relay) NO output side and the CVL (convection
element relay)
for 240 volts. Refer to picture for test points. )
If you have voltage present move to step 4
If you do not have voltage replace relay board.
4. Check the HTC (high temp cutout) for open circuit. HTC is a NC switch. HTC is located by
the latch assembly and has a re-settable switch. (see picture)
