Hi.. let me see if I can help... the first thing to check is to see if there is power at the outlet... if there is then we need to see if the unit is off, then we need to check to see if any fuses are blown.. let me know what you find on these three things and we can continue...phillip

thank you for verifying that... ok.. every component is started from the control board... so ..what we need to do is... using a volt meter... please check voltage in and out of the main power switch.. if you have voltage in but no voltage out...bad switch.. if you have voltage out.. then we need to check the transformer for voltage in-voltage out.. same process... if you have voltage in but no voltage out... bad transformer.... if you have voltage in and out... then the board probably is bad...it uses that voltage as power... now.. lets say if the transformer is bad... you don't want to just replace it.. because they usually do not go bad unless something drew too much voltage and caused it to burn out... by the schematic, it looks like the only item on that circuit is the board... so you're looking at probably changing both if the xformer is bad.. if it is good and the unit will not power on at all... your control board is bad... check voltages and contact me back with what you found... so we can continue...
