Customer Questions and Answers for Control Board by Whirlpool

Hello Patrick. There can be several things that can cause the board to burn out. If the motor is good, then a new control board WP8546219 should fix the problem. Below is the motor test from the manufacture. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html TEST #2 Motor Circuit Test This test will check the wiring to the motor and the motor itself. The following items are part of this system: – Harness/connection – Thermal fuse – Belt/belt switch – Motor – Door switch – Machine control electronics. See ESD information, page 1. 1. Unplug dryer or disconnect power. 2. Access the machine control electronics and measure the resistance across P1-3 and P1-4. See Accessing & Removing the Electronic Assemblies, page 7. ? If resistance across P1-3 and P1-4 is in the range of 1 to 6 ohms, replace the machine control electronics. ? Otherwise, go to step 3. 3. Check the wiring and components in the path between these measurement points by referring to the wiring diagram on page 2. 4. Check the thermal fuse. 5. Check the belt switch and motor. Access the belt switch and motor by removing the back panel. See page 8. Carefully remove the drum belt from the spring-loaded belt switch pulley, gently letting the belt switch pulley down. 6. Remove the white connector from the drive motor switch. 7. Using figure 6, check for the resistance values of the motor’s Main and Start winding coils as shown below. NOTE: Main and Start winding coils must be checked at the motor. MAIN 2.4–3.6 O Blue wire in back and white/orange wire START 2.4–3.8 O Blue wire in back and violet wire
