Question
Hi,

The furnace blower is not starting, the ignitor, gas, light blinks normal (fast), can hear the switch sound to engage the blower after the gas is turned on/ starts burning ...

Any ideas/ things to try?

Answer
Ron,
 I am not sure what you are saying.  If you are saying that the inducer motor runs, the Ignitor glows and the burner's start, but the blower (fan) does not start.....?  The first thought is the blower motor is bad.  If you have a fan switch on your thermostat and it is wired in, switch it from auto to ON.  If the blower (fan) starts and the above is true, it is either the board is bad or a wire is off or broken to the blower motor.
 If when you try the fan switch in the ON position and you hear the motor groaning it could be the capacitor.  So turn the power off to the furnace and first carefully reach in and turn the "squirell cage" that is the blower wheel the motor turns.  If it is hard to turn, then the motor has failed due to bearings, cannot be fixed unless you take it to a motor shop and wait a few days to a week ( usually) to have it rebuilt.  If it turns easy,and groans like it wants to start, you might take the capacitor to Granger ( I dont know what stores you have there to get these kind of parts) and buy a duplicate capacitor and install it.
 The capacitor is a silver can about the size of a ciggarett pack and has 2 brown wires attached that come from the blower motor.  It is held onto the outside of the blower assembly that the blower motor is mounted in by a sheet metal strap and 2 , 1/4" sheet metal screws.  It will say 5, 7.5, 10 or 12 MFD and then 370 or 440 volts.

Expertise

I am in Portland Oregon at Ben's heating 503-233-1779. I work days, so I can only answer early in the day or later in the evening. I only answer public questions for residential equipment. I am very well versed in gas, electric and heat pumps and will only answer residential applications. I have been known the past decade or so, by my employers as the guy you send when no one can figure it out. Trouble shooting is my special. I understand the physics behind air flow, refrigerants and electricity. I understand programmable t-stats, zone controls, economizers, fossil fuel kits and the engineering thought process in the wiring and construction of residential equipment

Experience

I was lucky enough to start in this field almost 30 years ago as an installer, for a company that installed the best duct systems I have ever seen, even to this day. The best ,as far as understanding the way air really flows through a duct system, from the return air to the very last supply register . They also had great pride and the duct work was put in, not only to last 50 years, but to look exceptional. Then as I started doing service work, I was again fortunate that I found a 3 year engineering class being put on be a man that was the educational director for the Entire united states for a society called " the Refrigeration Service Engineering Society " And for the next 3 years I schooled at night and practiced what I learned during the day, a great advantage over schooling and then trying to remember it years later.. Versed in duct design manual J heat gain/loss calculations.

Organizations
Refrigeration Service Engineer's Society

Publications
I have 2 inventions that have gone through the process and been recorded at the National Institute of Standards and Technology from start to finish and thus been invited to national innovation workshops by the dept. of Commerce and the dept. of Energy. They are waste heat recovery devices that N.I.S.T approved as valid and am currently looking for marketing partners to get this product into the hands of consumers and make a BIG difference in Energy savings for every Household and Eatery and take a big bite in the the peak hours power consumption that face our Utilities companies.

Education/Credentials
factory training in Lennox ,Rheem, Ruud ,Trane, Tempstar ,Carrier, Day&Night, Payne, Bryant, Coleman, Intertherm, York, Goodman, Ultra boilers, Unico, Mitsubishi,Sanyo, Taylor, Nicewonger, Navien. Associates degree in Refrigeration Engineering. Certified with Energy Department, Check-me Program, P.T.C.S (performance tested comfort systems ), have N.A.T.E. certifications in gas, a/c & heat pump.
