Wolff Tanning Bed Tanning Bed Bottom Lights Turn On But Top Lights And Fan Do Not?

Tanning bed bottom lights turn on but top lights and fan do not? - wolff tanning bed

I have an SCA Wolff System Series IV 424SL solarium. It is probably 13 years. The problem is that, when activated, the lights from the ground up perfectly, but did not initially work. The lights on top not easy or the fans. We have checked all outlets and the timer worked. I have a friend to watch the electrician could, but it would be for some ideas on where to start to be useful.
