The dryer does not provide heat at any heat selector position. The motor works, fuses, thermoswitches, timer, heater element all seems to check out.
There appears to be a switch connecting the backside of the heater element according to the drawing connecting the back side of the 240 but I am not able to find it. The power coming through the black wire and timer has power all the way to the heater element.
Where else could the problem lie? Thanks for the tip in advance.

Here are your parts Replacement parts for WHIRLPOOL LER7620LW0 | AppliancePartsPros.comHere is the wiring diagram http://www.servicematters.com/docs/wiring/Wiring%20Sheet%20-%203979703.pdfFirst try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker and the heating coil requires the full 240 volts. If this does nothing. Measure the voltage at the plug L1 to L2 should be 240 volts L1 to Neutral and L2 to Neutral, both should be 120 volts. If OK Unplug the unit and check the wires at the unit's terminal strip to ensure they are properly connected and none of them have burned off If OK Plug the unit in and check the voltage at the terminal strip. This is just in case you have a bad line cord. Be careful 240 volts is lethal. If OK Unplug the unit and check the heating coil and thermostats etc. for continuity. Heating coil, should be 12 ohms approximately. Thermostats and thermal fuse all should be 0 ohms. Be sure to disconnect one side of and device you are measuring this prevents reading an alternate/parallel circuit path. Also use your most sensitive ohms scale. There is a good Sticky at the beginning of this forum on meter usage. |
