connected to the oven control, and the display 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

 

 

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 supply

 

 

voltage output to the mercury contactor, replace the

 

 

oven control. If there is supply 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 should be as follows:

 

 

230V – 33 ohm.

 

 

Replace heating elements as needed.

Oven heats with

Mercury contactor

The mercury contactor has probably failed in the closed

switch off

 

position. If there is no voltage at the operating coil, but

 

 

there is high voltage output from the contactor, replace

 

 

the mercury contactor.

Intermittent heating

Thermal/overload of

The main fan motor is equipped with internal thermal

 

main fan motor

protection and will cease to operate if overheating

 

 

occurs. As the motor overheats and cools, this will

 

 

cause the heating system to cycle on and off

 

 

intermittently. Improper ventilation or lack of preventive

 

 

maintenance may cause this problem. Also, most of the

 

 

problem listed under “Oven will not heat” can cause

 

 

intermittent failure.

Conveyor will not run

Incoming power supply

Check breaker, reset if required. Check power plug to

 

 

be sure it is firmly in receptacle. Measure incoming

 

 

power, call power co. if needed.

 

Fuse, 10 amp

Check, replace if necessary.

 

Fuse holder

Check, replace if necessary.

 

Hi-limit thermostat, control

Check for voltage on both sides of switch. Terminals are

 

box

normally closed. If open, reset and test oven for proper

 

 

operation. If thermostat will not hold, and control box

 

 

temperature is not exceeding 140°F (60°C), replace

 

 

thermostat.

 

Switch, main fan

With power off, check continuity between switch

 

 

terminals. Replace as needed.
