I verified the blower/fan wiring and it became as tester101 said: a black twine was on the cool terminal. The black cord runs the blower on excessive velocity. A blue wire become on the heat terminal. The blue wire runs the blower on medium speed. A red cord become at the m1 terminal. The red twine runs the blower on low velocity (lowest speed). With thermostat warmness/off/cool switch set to warmness, and fan car/on switch set to vehicle, warmth runs generally: interior blower/fan is off, gas valve turns on, furnace ignites. After a few delay, blower starts offevolved and runs normally. Then, set thermostat warmth/off/cool switch to off. Gas valve turns off, blower keeps to run for a while, then blower shuts off.
With thermostat warmth/off/cool switch set to chill, and fan vehicle/on switch set to automobile, outdoor ac fan and compressor start and run commonly, inside blower in no way starts offevolved. Even as outdoor ac fan and compressor are going for walks, turning fan car/on transfer to on has no impact (inside blower stays off). Checking out: first i placed a jumper from g to r and depressed the interlock switch to allow strength to the gadget. After a completely brief delay (about one-half of to at least one 2nd), the inside blower/fan started up. I checked the voltage on the warmth terminal and determined 120 vac.
