How to troubleshoot dve52m7750v/a3 not heating. Already replaced heating element, thermal fuse and thermostat. I also checked resistance of thermistor at room temp.

Hi guys,

 

I recently moved homes, dryer worked fine until I moved. It no longer heats. I bought a replacement heating element which came with thermal fuse and thermostat. I am sure none of these had failed as there was still continuity between all 3 prongs of the heating element. And the fuse and thermostat still had continuity or wont blown. I replaced them anyways. I then measured ohm of thermistor and compared it to a chart I found online. I got 8.8ohm and house was around 80F. 

I also checked voltage of a relay at the pcb that connects to one of the wires to heating element. When I plug everything and turn on a cycle, I see 120V on all three prongs of heating element too. Shouldnt one of these be ground? If not, how can it get power and not turn on? 

Can someone guide me how to properly troubleshoot? I dont want to buy a new pcb if that isnt the issue.

I don't work on Samsung so can't be much help there specifically, but was the power cord changed and did you verify 240V to the dryer where the power cord hooks up? Should have 240V between the two hot legs and 120V from each hot leg to ground/neutral.
