Power Supply If there is sufficient micro-amp current, but the flame will not stay lit, check for proper polarity of the 120 VAC power supply. Ignition Control If there is sufficient micro-amp current, and the 120 VAC polarity is correct, but the flame will not stay lit, replace ignition control. NOTE: Check for proper ground connection on ignition control. NOTE: Flame should be lit at this time. Low flame is on, Temperature Control Check for 120 VAC at terminal #7 but no mai

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

Temp. display inoperative Display Transformer Measure the transformer primary for a nominal 120 VAC input, if voltage is not present, trace wiring back to the oven power source. Measure the secondary output, which will normally be 12-15 VAC. Voltage across terminals 1 and 3 on the time/temp. display should read 12-15 VAC. Terminals 1-2 and 2-3 should be 1/2 the voltage reading to 1-3. If the above secondary readings are not achieved, replace transformer. Temp. Display If proper vol
