Testing heating element


My heater is inop. Electric and above bathroom. Thermostat seems ok and calling for heat as it triggers both switches and sending 240 power to elements. I put an amp meter on wire from switch to element and didn't read any draw but line was energized. Appears to be two elements. How would I test them? I was able to put camera up there to take photo. But almost no room at all to pull the element. Blower and acoil in front and can't get visual on elements. Seems odd that both elements would be inop or maybe one had failed earlier. Is there any other test I can do before I pull apart.

Thank you. Couple questions. How would i know what a good ohm and bad ohm reading was. Also would i assume I would have to disconnect the power from those connections to get a proper reading?

You may be able to look-up the rated resistance on the net, or call the company that manufactures the heater and you will have to isolate the heater coil to test it.

If you have 240 volts at each coil and no amp draw then the coils, or a fuse link attached to them, are shot.
