Saunas

We have an indoor dry sauna with Bathology lighting system with its own control panel inside the sauna. The control panel is not turning on the lights. The builder has not been available for 5 months to repair it. An electrician looked at it and thinks the control pad just needs changed. Spoke to Bathology and they gave us the replacement part but the model has changed looks but they say it will work. The electrical companies though do not want to work inside saunas even though it is a sauna part by the same company.
