Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries ~~~
Can you confirm a couple of general things here, you state that when you switch on you can hear a sound, does this sound like a fan assembly running. However you have no lights or heating ?
ok can you confirm that all heater switches and the main power switch is switched on and that the thermostat is switched up to its highest?
