Very low voltage on baseboard heater
Hello,
I have had a baseboard heater relocated this summer, and it appeared to be working when it was installed. Recently when I turned it on, it didn't work.
I measure the voltage on the lines and it reads only 30V. There is another baseboard heater connected to the same breaker and it is working fine.
Can anyone provide suggestions?
Thanks

Did you turn the breaker all the way off then on? Were you using a digital multimeter? Is the heater 120 volts or 240 volts? How did you make the test, from what to what? Did you test before or after the thermostat.

Thanks for the reply.
Yes. I turned the breaker all the way off and then on.
I am using digital multimeter
The heater is 240 V
The heater has a built-in thermostat.
I disconnected completely the heater wiring from the cable. There are three wires from the cable, ground, red and black. I test the voltages btw all these lines. Between red and black, ~28 V; between red and ground, ~30 V; between black and ground, ~5 V.

If you used an analog multimeter your readings would probably be 0v so don't be fooled into thinking you have partial voltage. It's probably just the digital voltage meter reading insignificant induced currents
