Question about Soleus HM1-10-32 Heater
New heater and was working fine for a day. Suddenly stopped working. The heater is not powering on. The power light is not glowing. I have medium level knowledge about electrical circuits and hence opened the heater. What I saw inside was that the heater has a RT2A controller with leads such as 1 A 3 B, Voltage adjuster to adust the heating to low, high and eco and a Ball Tilt Switch. Everything looks fine. The voltage meter (power tester) has two leads. Unless I make contact at both AC lead points (similar to positive and negative points on a DC battery) the neon light doesnt glow.
A. I dont know where to check for the voltage
B. I dont know which one the following possibly can be problematic.
Thermostat / Power regulator / Voltage controller / Tilt Switch / Wiring.
Any help you can provide will be greatly appreciated.
If you can hear a "click" when you turn the temperature knob, and the unit is plugged in, chances are the heating has failed.
If you have a multimeter, unplug the unit from the wall.
Put the meter on R x 1000 ohms, and put the meter probes on each of the plug blades. Rotate the temperature control through it's range. You should have just a few ohms when the control has clicked (you really don't care at this point), as you turn the temperature control to a hotter temperature. You should have no ohms when turning the other way (this all assumes you are in a typical room temperature environment.).
If no reading is obtained, either the element has failed, the temperature control has failed, the "tip-over" switch has failed, there is a burned terminal in the wiring, or sometimes a heat fuse fails.
If it's the element or temperature control, it's probably best just to buy a new heater. The other three are identify and replace.
