Element Resistance Troubleshooting - GE Profile PP945 Technical Service Manual

Element Resistance Troubleshooting

WARNING: The power must be disconnected from the cooktop.
The resistance of certain elements and the continuity of certain element circuit wiring can be tested without
removing the cooktop from its installation. This test will aid the service technician in determining if the RPSM
or the DRM should be replaced. This test assumes the touch board functions properly.
