Baseboard heater wiring

So I have a problem but don't know why it's happening.

I want to move a baseboard heater that the builder put in. It has 2 red and 2 black wires and 2 ground wires that attach the heater.

Now, I want to put it in another location that has only 1 red and 1 black and 1 ground wire. When I attach it, the baseboard heater doesn't work. It only works when attached the the 2 red, 2 black, 2 ground. Why is that?

when you removed the heater from the original location did you twist the existing wires back together? the new location you want to install it is probably in series with the original location. Use a multimeter to determine where you have power and where it stops

Yeah I just left the original wires together and maretted them off. I don't understand what you mean when you say use a multimeter. What am I looking for?

This is my thought as well. (I'm electrician by trade.)

as the other poster mentioned, you can check the wires for voltage when on and continuity when off using a multimeter. This would determine which wires are the feed and which wires are going to the next baseboard.

Did you twist the two wires together (black to black/ red to red) when you marretted them off? Also when moving the baseboard those wires would need to be placed into a junction box and be accessible by code. (don't marrett them off and stick them into the wall)

From the pictures on the baseboard. one cable/wires (nmd-90) would be 240volt (1-red 120v, 1- black 120v = 240volt) The other cable/wires would probably be daisy changed to the other baseboard in the house


Hope this helps
