Question about Whirlpool LER4634J Electric Dryer
Hi and welcome to FixYa. I am Kelly.
No heat and the timer not advancing is usually caused by an open cycle thermostat. (Item 20) This link: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5151792&diagram_id=956658#d956658
It can also be caused by a defective high limit thermostat (Item 15 above link) and an open heating element item 17 above link.
Before you even try to take the dryer apart or attempt ANY repairs go to the main CB panel and cycle the dryer CB off by physically pushing the thermostat to OFF (manually resets CB) then back to ON, Test the dryer for heat. Sometimes one of the 2 breakers trips allowing the dryer to run but not heat.
You can download this job aid to assist in locating / replacing the failed part.
Disassembly order is Top, Toe Panel and Front Panel. Make sure to remove the 2 screws in the lint filter befor attermpting to remove the top.
Make sure to unplug the dryer before attempting any repairs.
Testing of each thermostat is done at room temp with one terminal disconnected with an Ohm meter. They should read continuity (ZERO Ohms) across the 2 terminals.
The heating element should also read a very low resistance across the terminals.
Note item 18 in the first link. Heating element wires are notorious for getting hot and failing at the heating element connections.
I do not at this point think you have a timer problem. There is a very remote possibility that you could have a bad motor switch.
Also check all connections at the dryer cord terminal block connection. These are known to also get hot from a loose connection. See item 42 this link for wire kit to fix the terminal block wires
