Hi, I have a Carrier Weathermaster 2000 Mod# 58TUA08014 Ser#
3496A08764. It runs fine for awhile but occasionally won't start until I go
downstairs and turn the power switch on the side of the furnace off and back
on. The problem now is becoming more frequent. It seems to do it most often
when the thermostat has cycled cooler all night so the furnace has been off for
awhile. I have taken the covers off and checked for loose wiring, etc. and
cleaned everything including all electrical contacts. Yesterday I did notice
one transformer on the bottom felt hot before I restarted it manually again
this morning. Today I checked it while the furnace was operating fine and the
same transformer was cool. The transformer is not named on the wiring diagram
but is on the right side and has a black & white wire going to it on top
and blue & red going to it on the bottom. Any advice? Thanks! Bill Hoidas
Have you checked to see if the fan motor is getting hot. Sometimes a system will shut down if the fan motor is causing the reset fuse to break the circuit due to heat. If that is the problem just a replacement of the motor will usually fix the problem.

As far as the mystery transformer goes im guessing for humidafier.the furnance is going into lock out line voltage resets this and lets it retry. dont know your level of skills but alot of times this is caused by flame sensor which is part of pilot assembly,metal rod that pilot passes electric signal back to control which confirms pilot lite. lightly sand rod that might get you goin
