Expensive shipping
I ordered what is called a thermostat but looks like a small resistor. I received the order on time and overall was very pleased. My only complaint was the cost of shipping. The part cost $4.50 and shipping was $5.00. It could have been put in an envelope with a stamp.

Googled why does my fan work but not the two light sockets.
Everything that came up, pointed to the thermostat wire, so I found the wire on my bath fan and ordered a new one.
Once it arrived I changed it out and both light sockets worked again.
Pretty easy task after watching a how to video on YouTube too.
