This is a Fisher Paykel. Sometimes when I start it gets hot, and sometimes it doesn't. There is no pattern that I can tell. Of coarse when it's not hot the clothes never get dry. It seems lately its not heating more than it is. Sometimes it will start heating and then stop after a few min. What should I look for to repair it? Thanks for any help.

I need an opinion. I think my problem is the timer. I can open the door and hold the door button down and push start and I can see the coils heat up. Then I can reach up and touch the timer knob and just put a little pressure on it either left or right, not even turning it, and the heater coils turn off. When I let go of the timer sometimes the coils come right back on and sometimes they don't. Does that sound like a bad timer? I have checked all the connections and all the wires seem to have good connections.
