Product review (5 stars): Don't be cheap - replace both parts with the real deal OEM parts
The thermal fuse blew on my dryer, and I considered 2 "frugal" repairs that would have been dumb, IMO:

bad idea #1) reset the "non-resettable" thermal cutoff.  Using a technique I won't describe, I was able to easily restore continuity. I reinstalled the cutoff fuse and the dryer worked.  Then I took it out again and ordered these inexpensive replacement parts. Just because continuity was restored doesn't mean that the part would perform it's actual function: to break continuity at excessive temperatures.  My house and family aren't worth the risk to save the price of a sandwich.

bad idea #2) only replace the thermal cutoff, and save the new high limit thermostat for the day that the original one fails.  Upon further consideration, I followed the instruction on the machine to replace both (see picture).  The original high limit thermostat could not be trusted anymore.  If it had done its job (break the circuit at 250F), then the thermal cutoff wouldn't have reached 352F in the first place.

I've seen some reviews that complained about not getting OEM parts. Some sellers are shady, I guess.  I bought from TOPPICKS (https://smile.amazon.com/gp/help/seller/at-a-glance.html?seller=ANWFIDLYBBZQN), and received OEM (Whirlpool / FSP) parts that look nearly identical to the originals.
