Disassembled and discovered this thermocouple is the wrong part, the threads are too small to attach. The manual says the appropriate thermocouple for my MI5036FBN is "Thermocouple (White Rodgers) 233-46501-15", or at least it's the only thermocouple listed. See photos for all evidence. UPDATE: I found out that my model/serial number requires the Honeywell version and it is not listed as "Thermocouple" but as "Bradford White ICON Natural Gas Pilot Assembly 233-47845-05". , which is why I overlooked this before! beware
