Intermittent Heating

Thermal/Overload of

The main fan motors and the burner blower motors are

 

Main Fan and Burner

equipped with internal thermal protection and will cease to

 

Blower Motors

operate if overheating occurs. As the motors overheat and

 

 

then cool, this will cause the units to cycle on and off

 

 

intermittently. Improper ventilation or preventive maintenance

 

 

may cause this. Also, most of the problems listed under

 

 

"Oven will not heat" can cause intermittent failure.

Conveyor will not run

Voltage Supply

Check incoming voltage supply at line 1 to neutral. There

 

 

should be a voltage reading of 120 VAC. If not present, check

 

 

breakers.

 

Fan Switch

See procedure for checking at beginning of section.

 

10 Amp Fuse

Check and/or replace.

 

Fuse holder

Check and/or replace.

 

Speed Adjustment

This is a 0 to 10 K ohm, 1 turn potentiometer. With power off,

 

Potentiometer

remove the black and white pot leads from the motor control

 

 

board at terminals P1, P2. Place the meter leads on the black

 

 

lead (P2) and on the white lead (P1). Rotating the pot., slowly,

 

 

from low to high, the meter readings should show an even

 

 

transition from 0 to 10 K ohms ± 5%. There should be no

 

 

dead or open spots through out the 1 turn of the pot. Check

 

 

both leads to ground. There should be no continuity to

 

 

ground. If any of the above checks fail, replace the pot

 

DC Motor Control

Check for 120 VAC input to the control board at terminals L1

 

Board

and L2. If not present, check wiring back to the fuse. If 120

 

 

VAC is present at L1 and L2, check both fuses on control

 

 

board (8A line and 1A armature), check the VDC output at

 

 

terminals A+ and A-. If 120 VAC is present at terminals L1

 

 

and L2, and DC voltage is present A+ and A-, but motor does

 

 

not run, check gear motor as follows.

 

Conveyor Gear Motor

If DC voltage is present at A+ and A- and the motor does not

 

 

run, first check the mini breaker and then the conveyor. Refer

 

 

to the next possible cause. Check the leads to the motor for

 

 

evidence of any shorts or opens, and each lead to ground.

 

 

Check motor brushes. From the top of the motor, rotate motor

 

 

shaft to determine if there is a locked rotor or a locked gear

 

 

box (use care so magnet and H.S. board are not damaged).

 

 

Replace motor as needed.

 

Conveyor

Check for any mechanical misalignment. Also, check for worn

 

 

bearings. A conveyor belt that is over tightened will cause

 

 

excessive bearing wear and sometimes, irregular speed.
