1993 Newmar Air Conditioner replacement

Need more info. You state it has an LCD tstat. Your year, they did not have LCD tstats so we need to find out what type tstat it has been replaced with. It can either be a 4 or 5 button CCC tstat. 4 buttons discontinued in 2001 and 5 buttons used from 2001 till about 2012. THAT determines what type replacement you need to go with. Also, the roof top units, you will NEED the model number. If a 500 series, it will take a different replacement than a 600 series. 600 series are lo profile PENGUIN units. Also, the footprint in the roof cut out for return and exhaust air may have to be modified when installing a newer style Dometic unit. Doug

This link shows a 4 button. The 5 button looks identical except it has the 5th (Zone) button.
