Welcome. My name is ***** ***** would be glad to assist.
Since you have a voltage meter, please do another test.
The top thermostat and element are the primary units and the bottom thermostat and element work once the top one is satisfied and reached temperature.
Only one element can operate at a time.
So, with the meter, turn the top thermostat all the way up to 140-150 and then read BOTH wires on the top element.
Do not read one side to ground, read between both sides and see if you read 240 volts.
Let me know results and we can continue
See the below picture for more information on how they are setup and what to look for:
Ok, if you do not read 240 volts on the element, then the thermostat is not working.
The thermostat measures the temperature and then closes contacts to provide the heating element with the needed voltage.
Turn the dial all the way up on the thermostat and listen carefully for a clicking sound, that is when the thermostat should power the element.
The reason you do not read an element on one side at a time to ground, is because the power on one side will actually travel through the element to the other side.
That is only 1- 120 volt source.
If you look at the diagram I posted, you will see where to measure the top side of the thermostat for 240 volts.
Then the bottom side for 240 volts.
If the bottom does not read, the thermostat is bad.

Ok, very good. Glad to assist
