help with my Kenmore stack washer & dryer?

I have a Kenmore Heavy duty, super capacity washer & and dryer stack unit. model # is 417.97802301. My dryer needed the piece that the tub spins on. It snapped clean, so I repleased it. I put the whole thing back together and tried it and it spun fine, but now it had no heat. So I was told to replace the thermal fuse, still no heat. I have no idea what it could be. I still use the washer and just hung up all the clothes to dry until I can pay someone to fix the dryer. Now the washer leaks water out of the holes on the back panel and flooded my basement. So now I go to the laundramat, to wash and dry my clothes. Way to expensive. The kicker of it all is that this washer and dryer is 2 years old and it came with a 1 year warrenty. Please help. I am sick of taking this thing apart.
