Hi, I am getting very minimal heat. The elements are ok so I,m thinking could it be either the thermistor connected to the heater elements, i have continuity across this, (has a red “button” on the top which is loose, I have tried to push it in thinking it may reset)am getting only 1 volt at this, or the temperature limiter on the top of the element box, which also has continuity. There is a thermistor in front of the fluff filter, but i think thats for the fluff filter warning light. All filters and condenser have been clean and the water hose has been blown through. Any thoughts would be appreciated. Thanks
