This is an a double wide mobile home. The two sides of the kitchen are on different circuits. When both Breakers are on one side reads 120 hot to ground 120 neutral to ground 240 something hot to neutral. When just one breaker is on it reads 120v hot to ground nothing anywhere else
Electrical – see 240v between hot and neutral when one breaker is out in the mobile home

Based on your updated readings (120v between h1-h2, 120v between h2-neutral, and 240 between h1-neutral), it looks like Hot2 and Neutral have been reversed. Shutoff the breaker, verify there's no voltage, open the outlet, and correct the wiring so you can dry clothes without getting zapped. In the end, you should have this:
It sounds like the neutral connection is bad, but not totally open-circuit.
As I understand it american driers normally have the high-power stuff connected between the two hots and the control system connected between one hot and the Neutral.
With the dryer disconnected, the bad neutral is enough to give you correct voltage readings on your high-impedance multimeter, but when you connect the driers controls. it drags the neutral up to the same voltage as one of the two hots.

Best Answer
Neutral to ground should not be 120. It should be at (or very near) 0. Neutral and ground are generally bonded at the service panel. When only one breaker being on causes this (and the other doesn't), it seems unlikely that you have lost your neutral service from the supplier. There is likely a fault on the neutral associated with one of the circuits. It's also possible that there is a faulty or mis-wired MWBC (explanation of MWBC here).
You could try disconnecting the wires from the breakers in the service panel and testing directly from the breaker to the neutral and ground. If everything tests as expected, you're looking at a wire fault. Otherwise, the wire isn't the first problem to fix.
