Question about Soleus HGW-308 Mid-Size Heater

No heat generated by Soleus HGW-308 Mid-Size Heater

My wife has been using a Soleus HGW-308 I purchased for her every day for ~1 month. As she ususally does, she had had it on in the morning, then turned it off to go have lunch. When she came back and turned it back on (after ~1 hr), it would not generate any heat. The power button indicates that power is still getting to the unit. When I turn the nob to adjust the heat, I can hear it clicking on or off, so the thermostat seems to be working, so might it be a short to or in the heating element(s) itself?

How can I troubleshoot this further? I have basic skills soldering, so may be able to do simply repairs if I can find the problem.

My cold wife and I thank you!

    Wonderful! Thank you very much!

    I'll isolate the problem, and simply replace the part (or unit if that's what it turns out to be).

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.

Contact the place you bought the curler and let them know what happened. If you have a manual, contact the Vidal Sasoon and tell them. If you don't have the manual, look them up on the internet and contact them.

Vanguard wall heater pilot will light but when to turn on heat it goes out. Thermocoupler??

This is a very good possibility and depending upon the year they may call this part a flame generator. So ask for both when purchasing. Before you run out and purchase this take five minutes and try this, I use steel wool or light grit sand paper and clean up the bulb end of the thermocouple then place it top center of the flame as this is the hottest area of the flame, now with a small wrench check to see that it is tight in the gas valve. Now try lighting the pilot and then the furnace. Some times a simple cleaning and tightening can cure this problem. If not now you can go and purchase a new one.
