Temperature Control Board

Check for 120 VAC input to temperature control

 

 

board. If not present, check wiring from fuse holder

 

 

to temperature control board. Turn the temperature

 

 

adjustment dial to the maximum temperature

 

 

position Check for 120 VAC at coil of mercury

 

 

contactor(s). Next, short the leads of thermocouple

 

 

on the temperature control board, check for 120

 

 

VAC at coil of mercury contactor(s). If voltage is not

 

 

present, replace temperature control board. If

 

 

voltage is present proceed.

 

Temperature Control

Potentiometer is 0 to 2.5K ohm. WITH POWER

 

Potentiometer

OFF: remove the leads from the temperature

 

 

control board terminals 1, 2, and 3 and measure

 

 

ohms from black to white leads. The ohm reading

 

 

should be 0 to approximately 2.5K ohms as the dial

 

Thermocouple Probe

Remove thermocouple leads from the temperature

 

 

control board, and measure the millivolt output of

 

 

the leads. Refer to chart in adjustment section for

 

 

proper millivolt readings.

 

Mercury Contactor(s)

Check for 120 VAC to the contactor coil. If voltage

 

 

is present and contactor will not activate, replace

 

 

the contactor(s). Also check each contactor for

 

 

proper high voltage input and output.

 

50 Amp Fuses

If there is no high voltage input to the mercury

 

 

contactor(s), check the 50 amp fuses and replace if

 

 

necessary.

 

Heater Elements

Check the Amp. draw on each hot leg for proper

 

 

load. Check the specifications plate for rating

 

 

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

 

 

the individual elements for opens, shorts, and

 

 

proper resistance . To check resistance of the

 

 

elements, turn off the power! Remove all leads

 

 

from the elements and use an accurate digital

 

 

VOM. The element resistance should be as follows:

 

 

208V - 9.8 ohms approx. 220V - 10.5 ohms approx.

 

 

240V - 13 ohms approx. If all readings are not

 

 

correct, replace elements as needed.

Oven heats with switch

Mercury Contactor(s)

The mercury contactor has probably malfunctioned

off

 

in the closed position. If there is no voltage to the

 

 

operating coil, but there is high voltage at the

 

 

contactor output, replace the mercury contactor.

Conveyor will not run

Voltage Supply

Check incoming voltage supply at line 1 to neutral.

(S/N 100-4389)

 

There should be a voltage reading of 120 VAC. If

 

 

not present, check breakers.

 

3 Amp Fuse

This conveyor fuse is located on the front panel.

 

 

Replace if defective.

 

Fuse Holder

Check and/or Replace.

 

Conveyor Switch

Same procedure as for fan switch.

 

D. C. Motor Control Board

Check for 120 VAC input to D. C. control board

 

 

across L1 and L2. Check the 3 amp fuse on the D.

 

 

C. control board. Check for D. C. voltage at

 

 

terminal F1 and F2. Voltage should be 10 VDC +

 

 

10 steady. If this voltage is not present, replace D.

 

 

C. control board. Check for D. C. voltage output to

 

 

the motor across terminals A1 and A2 (this voltage

 

 

should be approx. 125 VDC at maximum conveyor

 

 

motor speed).
