Product review (1 stars): condenser dryer -- 7 seconds on / 15 seconds off - enough to drive me crazy!
For months I have been attempting to determine the source of a cycle on / off and now conclude the issue is the Haier combo washer dryers in the condos.  The "condenser dryer" cycles on for 7 seconds and off for 15 seconds for the 60 minutes or the 120 minutes of the dry cycle.  The neighbor is more likely than not completely unaware of the sleep deprivation caused by the combo washer dryer.  The units are designed specifically to be used in multi family buildings but without the welfare of the neighbor in mind.  Otherwise the units do appear to wash well but do not dry well and do not remove lint.  The wash / dry cycle is 3.5 hours.  Good experience for future housing.  Never again.  The washer and the dryer and the dryer vent all serve an important purpose.
