At the end of 6 seconds, the hot surface igniter must sense a flame, or, the ignition control will go into lockout. (The ignition control requires a minimum of 0.8 microamps D.C.) To check the flame sensing operation, connect a digital multimeter (capable of measuring D.C.
  • Page 7 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.

Motor Control Board Place the test meter probes on terminals A+ and A-. (With speed potentiometer set to maximum speed (Approximately 2 min.) The meter reading should be approximately 100 VDC ( 3%), if voltage is not steady within limits, then the board is probably bad.
  • Page 9 Temp. display Display Transformer Measure the transformer primary for a nominal 120 VAC input, inoperative 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 temp. display should read 12-15 VAC.
