Had the same prob. A lot of units 10 years or less have two separate heating strips when you first turn on the unit both are active once it reaches desired temp it alternates between the two to save on power. If one of these is bad it will blow cold when it cycles to it and warm back up when it switches to the other if it is still functioning. Hope this helps
