Sportsfan for Model Number rf385pxeq - whirlpool accubake ready to buy a switch as RR (8") is bad. burner sparked due to loose harness clip. I tested ohms to double check the rest of the switches as several look burnt in the back. tested l1 to h1 and h2 to l2. How do I test voltage? I tried the same route and they all read differently. Can not get voltage reading across defective switch of course although burner works. Nor on LF which seems hotter than whatever we set it to cook. LR i show 115 and 115v with 240v with switch in on position. RF reads 101 and 101 with no voltage in on position.
Answer Sportsfan, You're on your wat to a proper diagnosis. To conduct a voltage test at the infinite switches, you first need to be careful, don't short anything out, including yourself. With a meter and power to the range on, you should read 220/240 VAC across the L1 and L2 terminals of each switch(an extra step, check each terminal to chassis ground, meter should indicate 110/120 VAC), with the switch turned on to a high setting(so you get a proper voltage reading) You conduct the same test: Across H1 and H2 terminals, you should see 220/240 VAC, and 110/120 VAC from H1 to chassis ground, and H2 to chassis ground. The L2 to H2 circuit through the switch is the "cycling" circuit, so the voltage on the H2 terminal to chassis ground will cycle off and on, to control the burner and heat. We'll be sending you the wiring information for your stove, and that should be pretty helpful to you. Read More... Answered by AppliancePartsPros.com | Friday, November 16, 2012
