Electric Dryer.
I've just performed the following Checks:
Element p/n 279838/3403585 (Heating Inlet) ...
Good Continuity @ 11.4 ohms (Schematic says should be 7.8 to 11.8 ohms)
Voltage...Zero Volts across terminals, 120v to Ground (Element housing).
Thermal Cut-off p/n 3977393 (Heating Inlet, Top) ...
Good Continuity
Voltage...Zero Volts across terminals, 120v to Ground (Element housing).
Hi-Limit Thermostat p/n 3977767 (Heating Inlet, at Element) ...
Good Continuity
Voltage...Zero Volts across terminals, 120v to Ground.
Thermal Fuse p/n 3392519 (Exhaust Outlet) ...
Good Continuity
Voltage...Zero Volts across terminals, 120v to Ground.
Internal Bias Thermostat p/n 3387134 (Exhaust Outlet) ...
Good Continuity
Voltage...Zero Volts across Large terminals, 120v to Ground. Small Terminals Infinity/OPEN.
Continuity looks good, but I'm not getting 240v at
any point.
Found the Wiring Schematic in the upper compartment containing the Start Switch and Timer.
According to the Continuity Chart at the top of the Schematic, with the Timer set to "Auto-Reg/High" I should be reading an open circuit between BK-BU and BU-V. I read a closed circuit between BK and BU (as I said, the circuit read
closed). The next column contradicts it by saying the BK-BU circuit
should be closed. I get the same results with the Timer in the "Timed-Reg/High" position.
HUH???
Am I reading the chart wrong?
My understanding of the caption "BK-BU-V" is: BK(Black) to BU(Blue), BU to V(Violet).
Is this correct, or am I missing something here?
I maintain a $2.5 million helicopter, and regularly use Schematics, but this Whirlpool Continuity Chart has me confused due to the above.
Or do I in fact have a bad Timer?
