My dryer stopped working. i suspected a blown fuse and I was right but I replaced it and it still wont work. I checked the wires at the top of the box and confirmed 240v, but i can’t figure out what to test to confirm voltage after the fuse. can anyone tell me what wires to test for checking voltage after the fuses, and why isn’t it working? thanks

What voltage
do you have at the dryer receptacle?
You may need to move the dryer, remove the trim plate, and even pull the receptacle to have access to the terminals in order to test this... but that's where it counts.
I would also check the downstream side of each fuse, or course... not sure if that is what you did.
I checked downstream but cant find any voltage, im not sure of what wires i'm supposed to test, there is one red and one white from two fuses.
Anotated picture
From A to B should give 220. A or B to C should give 110.
But you won't get anything to either of them until the knife switch is closed. There is typically a mechanical interconnect, that won't let you open the door, if the knife switch is closed. Look and you should see it, and be able to figure out how to by pass it.
Once the knife switch is closed, you should be able to get the readings.
Aside from the fuse, electric connections shouldn't become problems, usually.
My dryer is gas, but it has some kind of heat sensor that can break. If you have time, research at the repairclinic.com. This sensor prevents overheating from clogged vent. The dryer is over 15 years, so I just replaced this sensor as a prevention.
Thermal fuse
They are thermal fuses, available from radio shack inexpensively, (less than $3). They have no moving parts, don't wear out, and don't need replaced unless they have fused. Typically the dryer will still tumble but not heat when they fuse.
I had to replace them in my minivan every year or two when I lived in Vegas. Because people wouldn't roll down the windows, and turn the fan to high, when they started the airconditioning. The fuse is a 150-degree one, and the inside of the car will reach 140-dgerees. So the bit of added heat from the fan speed resistor would blow the fuse, and the fan would run only on high.
