Ok, now you are just being silly. There are plenty of 24" dryers in every brand on the market, so lets not dream up ways of getting around the fact that your unit is obsolete now. Puh-leeze...deal with it.
You will have to upgrade your wall plug to a 240 VAC 30A outlet, as there are no more 120 volts models around that we know of..the DOE practcally made them obsolete due to their energy wasting capabilities.
The timer is nowhere to be found. When you cue the database on Whirlpool, this is what you get:
"Timer - no longer available - This part has been permanently discontinued by the manufacturer and we don't know of any source for the part"
The original part number is 693550 from Whirlpool. Not every thing is repairable. We would know if it was.
