I found a source on the internet for a 98 deg C thermal fuse and have ordered 10. They do not come with the connectors or plastic sleeve, but I will get the connectors at an auto parts store, and reuse the sleeve.
They have different quantity pricing, 10 are $1.10 each.
The site is
Goodmans
Hopefully they will be at home when we get back on Monday.
I used my last spare in Quartzsite, I think it was the high winds.
