Hello -
I have Byrant Plus 90 398A furnace.
Lately, I noticed that my thermostat (Honeywell Chronotherm IV Plus) has no display. I am suspecting this maybe caused by blown furnace fuse. I took off the front cover of the furnace but could not find the fuse.

Here's the picture ==> http://i283.photobucket.com/albums/kk300/stk7105/Furnace/Circuit.jpg

Where is the fuse?

Thanks in advance.
