Product review (1 stars): JUNK
Did not last 2 weeks.  DO NOT BUY this piece of junk.  I am an electronics tech and got the replacement parts-  the thermal cutoff for the top of the heater plenum and the high limit thermostat/switch that is located at the bottom of the plenum.  Replaced both.  Threw away the bad thermal cutoff (top switch) and put in the new parts.  Kept old high limit thank goodness.  Now have to go buy new high limit.  Will go get OEM from Marcone or Grainger or SEARS.  Don't give a crap about price now.  Junk parts give web buying a bad name.  No recourse.
