thanks in advance,

Have you check the fuse on the panel yet?

thanks

Checking just the vent hose for clogs between the dryer and wall may not be sufficient. You need to check all the way through the exhaust duct to where it exits outside. However, if the machine is running, tumbling the clothes and they're completely cold after several minutes, it's definitely not heating and a clogged exhaust won't cause that directly.

A 3-year-old dryer should have a non-resettable thermal fuse as part of its overheat protection. If the exhaust clogged or the operating thermostat failed and the machine overheated, the thermal fuse would blow and require replacement, after fixing whatever caused the overheating. However, in most cases the dryer is completely dead if the thermal fuse blows.

Other causes of not heating would be a bad timer, a bad temperature selection switch, a bad operating thermostat, a bad high-limit thermostat (which is separate from the aforementioned thermal fuse), or a burned-out heating element. The heating element should last longer than 3 years. Premature failure of heating elements is often caused by constant overheating due to a clogged exhaust.

thanks in advance

The next step would be disassemble the dryer and check the components that I outlined previously.

If so, confirm there's voltage across the power cord terminals.

Or is that a temp selector at the left side, with push-to-start being part of the timer knob?

Set your volt/ohm meter on ohms at the highest scale.

Remove one wire (blue and red) from each component, check for continuity across the component terminals (blue-blue, red-red). If the meter reads 0, it's good. If the needle doesn't move, reads infinity, it's bad.

The thermal fuse likely is good, the dryer usually wouldn't run at all if it's not.

You can pull all the wires and remove the element housing, slide the element out of the housing and visually inspect if it's broken.

you the man......WOW. I truly appreciate the time and detail you put into this.
the temp selector at the left side (push-to-start)is part of the timer knob.
is there anything else I need to look at on the right hand side of the dryer (I noticed all testing is done on the left side). I don't mean to question you but better yet, want to educate myself.

thank you soooooo much

where do you suggest I purchase the faulty parts?

The thermal fuses shouldn't blow unless something else fails. The operating thermostat is supposed to trigger first of course to maintain the correct drying temp. The high-limit triggers if airflow is blocked and the element overheats. So theory goes that if either of the thermal fuses is blown then the operating thermostat (and/or the high-limit) is also bad.

The thermostats are bi-metals. They can also be tested by placing face-down in an electric skillet or a skillet on a stove and heating, testing with an ohmmeter if they cut-out. You'll hear a faint click. If it clicks, but still tests with continuity (doesn't cut the circuit), then it's bad.

The operating thermostat likely has a bias heater that mounts around the disc, activated by the temperature switch for lower heat settings, tricking it into triggering at lower than the rated temperature. The bias heater isn't involved in your no-heat situation, this is just additional info. Earlier designs had multiple operating thermostats, each one triggering at a specific temp (125°F, 145°F, etc.) for lower temps. Bi-metals are typically stamped or labeled with their cut-out temp and differential. L155-20 for example would mean it turns the heat off at 155°F and back on at 135°F.

on the thermal fuse, I removed one blue wire and then set my meter to continuity, touched both terminals and there was continuity (beeped)...there was some clicking but don't know if it's because I did not touch the prongs properly on the terminals.

on the operating thermostat I removed one red wire, set my meter to continuity, touch the other red wired terminal and there was continuity (beeped)

I did not remove the purple wires but when I check for continuity across both purple terminals, there was no continuity (no beeping) Since you did not mention the purple wires I suppose they are
not to be tested this way.

on the upper thermal fuse, I removed one red wire and then set my meter to continuity, touched both terminals and there was continuity (beeped)

the high limit thermostat has two terminals (the bottom terminal touches an element terminal as well)
on this component, I removed the upper wire (red) and checked for continuity with the other terminal (which is also connected to the element terminal) and there was continuity (beeped)

on the element terminals which has three terminals (the one closest to the inside of the dryer does not have a wire) I removed the red wire (seen in photo) and check for continuity with the two other terminals and there was no continuity (no beeping). I tested the non-wired terminal with the top terminal (orange wire) and there was continuity (even with the orange wire removed.
no continuity when testing the non-wired terminal with the red wired terminal (red wire on or off).

Hope I did this correctly.

Please advice?

I replaced the element ($38~ shipped )and it did the trick. Thank You so much for such detail and time behind this.
