I'm trying to trouble shoot a Patton 220v/amp portable heater for a friend.She said that in the past sometimes wiggling the knob would get the heater to come on, but not anymore.So that seems like that would the obvious problem,but when I turn the knob on I get voltage to the other side. I get voltage to both sides of what i think is a thermal cut out and at the element. Seem to have voltage everywhere! But the fan never comes on either. The element looks good and I get a proper resistance of about 15. It's a 4000w heater. Any ideas for me?
Hi,
Yes it would seem that the thermostat or the knob would be the problem...when checking for voltage you need to check for 220v across the two terminals for the heating element. You will have 120 feeding back and forth all over the place but the fan and element will only work if they have 220... so you can have voltage and it still not work...
