Aha! when i first checked the unit over the inverter worked ,and so did everything else at least it made a noticeable noise, now there is no noise coming form it. If i put my ear down to it i can hear a small buzzing sound. the switch is on and both little white circit brakers are pushed in. Is there something inside that inverter i should look at ,or is the inverter shot.what next should i be looking for .Oh ! the two little fans up in the corner of the front windows stopped working also, i never mentioned that in my original post,. there were things on this unit that i could not try because the seller had it winterized and i had to take his word ,that every thing worked.And ,by the way,thanks for all the infomation so far .You told me things about this unit that ,i am sure, the seller didnt even know. thanks again.
