Hello,
As long as your getting 240 volts at the dryer terminal block, your breakers are fine. I would check the thermal fuse again and if its blown again, you will have to clean out your exhaust vent. If this vent is clogged the thermal fuse will keep blowing. You can try disconnecting the vent from the dryer to see if it blows again if thats the problem.
