24VAC is present, check for a read-out on the

 

 

display. If there is 24VAC supplied, but there is no

 

 

read-out on the control display, replace the oven

 

 

control.

 

 

If there is a read-out on the control, set the control

 

 

to maximum temperature (see installation

 

 

operations manual for temperature adjustment).

 

 

With the control set at maximum temperature,

 

 

check for supply voltage at mercury contactor. If

 

 

there is voltage at the mercury contactor, proceed

 

 

to “mercury contactor” for next check. If there is no

 

 

voltage at the mercury contactor, trace wiring back

 

 

to the oven control. If there is no voltage output at

 

 

the oven control, check the read-out on the

 

 

control. If the control reads “PROBE FAIL”, this

 

 

indicates that the thermocouple has failed or

 

 

become disconnected from the oven control.

 

Thermocouple

Check to be sure that the thermocouple is

 

 

securely connected to the oven control. If the

 

 

thermocouple is connected to the oven control,

 

 

and the control indicates “PROBE FAIL”,

 

 

disconnect the thermocouple from the oven

 

 

control and measure the resistance of the

 

 

thermocouple. The thermocouple should read

 

 

approx. 11Ω. If these readings are not achieved,

 

 

replace the thermocouple. If these readings are

 

 

correct, proceed.

 

Oven control

If the thermocouple checks good, but the oven

 

 

control display indicates that there is a

 

 

thermocouple failure, replace the oven control. If

 

 

the oven control indicates a temperature reading

 

 

but the oven will not heat, proceed.

 

Thermocouple

WITH POWER ON AND THERMOCOUPLE

 

 

ATTACHED TO THE OVEN CONTROL: Measure

 

 

the DC millivolt output of the thermocouple. Refer

 

 

to the thermocouple chart (located in the

 

 

“Removal” section of the manual) for proper

 

 

millivolt readings. If these readings are not

 

 

achieved, replace thermocouple.

 

Oven control

If the thermocouple checks good, but there is no

 

 

voltage output to the mercury contactor, replace

 

 

the oven control. If there is voltage output to the

 

 

mercury contactor, proceed.

 

Mercury contactor

Check for supply voltage to the contactor coil. If

 

 

voltage is present and the contactor will not

 

 

activate, replace the mercury contactor. Also

 

 

check each contactor for high voltage input and

 

 

output.

 

Heating element(s)

Check the Amp draw on each power leg for proper

 

 

load. Check the specification plate for rating

 

 

information. If the amp draw is high or low, check

 

 

the individual elements for opens, shorts and

 

 

proper resistance.

 

 

WITH POWER OFF: To check resistance of the

 

 

elements, remove all leads from the elements and

 

 

use a digital multimeter.

 

 

The element resistance is should be as follows:

 

 

208V – 27 ohms approx.

 

 

240V – 36 ohms approx.

 

 

Replace heating elements as needed.
