You can contact Manna Pro for their take on the situation but they didn't help me when it was the fan. It never hurts to try though!
It's heating up but the fan isn't working, right? It sounds to me like the fan, the wiring to the fan came loose, or something on the electric board got messed up.
I say this because mine did the same when I dropped one of my incubators and there was damage to the fan. The incubator was still heating, and the digital components were all working but the fan was "haywire" so the incubator would overheat and the alarm would start going off.
I couldn't readily find replacement parts for the incubator anywhere but eBay but this was quite some time ago so that may have changed.
If you know anyone really handy with electronics it could be something as simple as soldering coming loose on the board. I AM NOT ONE OF THOSE PEOPLE. My Dad is SUPER handy with tiny computer bits and soldering but I did not inherit that gene, lol.
Alternatively, if you know someone moderately good with electronics, you can just order a replacement fan (I can't remember if they came with the wiring harness).
