I have a Frigidaire Dishwasher , mod# GLDB653AS0 . The dishes are not drying properly. I have tested the circuit and when I turn the control to drying with the door closed , I recieve 120Vac as I should. I also checked continuity on the the heating element , and recieved an ohmic value . Can the element open and fail as it heats up? Is there anywhere else in the the circuitry that could be failing if it's not the heating element? Thanks for your help, Rocky Granger
