Anyone had a problem with Manrose bathroom extractors?

Hi, I am not an electrician, just an interested amateur, but I am having problems with a Manrose extractor and I feel I might be getting fobbed off by the manufacturer.
I could smell a burning smell in my ensuite and narrowed it down to the Manrose extractor. I took the cover off and the circuit board cover and could see the plastic had browned and started to melt where it was next to the resistor.
I contacted Manrose and they said it was perfectly normal as the resistor gets hot! I was shocked that it gets so hot the plastic melts but wanted to check with the experts that I'm not overreacting.
I have attached a picture and would appreciate your thoughts?

It looks like the resistor and the adjacent electrolytic capacitor have been bent over, probably during installation, with the resistor in contact with the plastic and the capacitor close to, or touching, the resistor. Neither are good.
Installer wasn't fussy about identification of incoming cables either, as far as I can make out.

Its a common feature of Manrose and a few other makers of timer boards on mains fans.
Eventually they die, usually a long time after the warranty period. So nothing much to worry too much about!
