Air Conditioners Pre-Purchase Advice

Room Air Conditioner Units with Electronic Controls

  • May stay off after return from a power failure until manually reset.
  • May also pose a problem when using timers (Shabbos clocks): the unit will turn off as set, but will not turn back on at the set time unless manually reset.


  • Contact the manufacturer for information on which models may have this feature.


  • Star-K is pleased to announce that in response to our suggestions, GE has modified its 2004 (and later) electronic room air conditioners so that they will now return to their default position. This means that on Shabbos and Yom Tov, the air conditioners will still function after being off due to a power outage or use with a Shabbos timer.
