Water temps were down on my boiler this morning. Temp. should read 188 but actual reading this morning was 148. Thought the wood may have bridged thru the night but I don't think that was the case as my wife informed me that the temp was 141. I had this problem years ago and it was do to clogged flue. When I get home tonight I will clean the flue and check the blower. The blower seemed to be running fine this morning but the fins may have collected too much dirt to blow enough air into the firebox . How would I know if the Ranco Tstat is bad? Any other things that I should check for?

We'll first ensure the water temp is actually what you think it is. Next make sure that the blower is blowing. A clogged flue could very much choke a fire so that it couldn't produce good heat. If the blower is running and the water temp is below the high set point then the aquastat is working fine.
