Hi,
I'm new to this site. I have a honeywell thermistat. It's display is off/blank. I've spent a good part of the morning trying to find info for this product. I've been wanting a schematic on line. Can't find one. Troubleshooting tips suggest checking the fuse. There is no "F" ref des on the pca. There is a "RT" (thermistor). I've tried finding some info on the subject including the post "working of thermistor" by "hbkamit". The only way to test it is to use an external heat source (stove top). Is this really the only way?
Thank you
