Hi,

Perhaps he has gas appliances ?

The dryer motor and timer is on 120 but heater element is 240
so his clothes would take longer to dry.

I agree with other post that he could have lost another part in the amp
or the main transformer has a short in the primary.

He could remove the transformer and bench test it using
small ac power supply to input 1-10 volts to the transformer primary
to test is in a safe way.

But if it were the pole transformer don't you think he would have
mentioned that half his lights don't work and that the stove, hot water
heater and dryer aren't working like they used to?
