Radiator fan quits

It’s 110* in Phoenix, driving in traffic. Fan operates normal. I can see/hear it turn on. Then for no apparent reason it quits working. Bike got to 223* when I coasted to the shoulder to camp for a bit. Did it a few times last year, nothing in the last 7-8 months. No error codes other than high temp. Anyone else??

99% It’s the automatic fan breaker. Chances are it’s having an internal failure when it heats up, trips, fans turn off, breaker cools, it engages again, fans turn back on.

But a new breaker, replace, test, if that’s not it then have a dealer go through it.

Only time it would give a code is if there was an electrical malfunction in the ecu not telling them to turn on.
