Blower on furnace hums and doesn't start
I am having problems with one of my two furnaces. When the thermostat
kicks in, the furnace will light, but the fan won't kick in. Then the furnace shuts down. If I turn off the heat (i.e. not on heat or cool), and turn the fan to "on", it just hums (the other furnace works fine and the fan will run). There is a solenoid that clicks, then the humming. The fan itself turns effortlessly. Do you think this could be a problem with the capacitor, solenoid or transformer? Also, I have been having another problem (probably unrelated?) once a year every winter when I first start the furnace. The fan doesn't want to kick in but I didn't notice any humming - this appeared to have something to do with that timer-like dial (is it a temperature limit switch?). Two taps with the end of a screwdriver and I'm usually OK for the year. Any ideas on either problem? Thanks. |

Too many variables to diagnose by remote control like does the blower (fan) motor have a start cap , run cap , both or neither (blower motors can be any of these). Could be a cap problem , relay problem , open start winding or none of these -again depending on your equipment. The best bet is call in an HVAC tech to take a look and I hope your not hitting the fan limit switch with that hammer as it is also a safety device :-( . Henry |

Thanks What you need is to get rid of that dinosaur, your throwing half the heat literally right up the stack, wouldn't it be better to put the $700 it would cost to solve your current delema towords a new furnace that at a minimum cuts your operating costs by 30 cents on your heating dollar., and realistically can average 45 cents over your current system and thats just a 2stage 80%er with a variable fan. Now for smidge or two more I can cut your wasted energy down to 3 or 4 cents on your heating dollar instaed of ****ing away 45 cents or better, on a really cold day you could ****away 50 or 60 cents on the dollar. Uses 60% of the electricty of a standard furnace, for what it costs to run your blower for 3weeks I can run this fan for a year or more. The higher your utility bills are the quicker the payoff in energy savings ; open a savings account and deposit the difference your heating bill would normally have been. At the end of the season you can take a nice little weekend mini vacation somewhere. Its money you would have had to have spent anyway. Yes...your welcome. |

Blower on furnace hums and doesn't start
If you live in or near a decent size town, and really know how to work
electricity safely.... Lock it out, mark both ends of all connections, pull the fan motor ( take fan off) and the capacitor and take them to your local electric motor rewinding shop. Look for sign that says "counter" in some form. Wait in line patiently, be nice and offer the guy a soda or coffee.They will be able to quickly test both (because they have to disprove 'returns') and sell you the right one wholesale. The small motors are not rebuilt, but replaced, should be $35 (often) to $75. It's not rocket science, don't get killed. Tim S. wrote in message ...

They are cheap enough to take the gamble. If that dont fix it, the fan motor is probably shot. Take out the whole blower and take it to a motor repair shop and have the motor tested and repaired or replaced. Blower removal should not be that difficult. Probably 4 bolts, and the wires. Of course shut off the power @ the breaker when you remove the wires. |

Hi,
First, when it's humming trying to go, give a gentle push and see what happens. If it runs, capacitor or the cetrifugal contacts inside the motor housing needs cleaning.

I want your wife or girlfriend to come over to my house and trouble shoot a electrical problem on my furnace and your not invited and she will have to work on it alone with no help to tell her what to touch or not to touch while the power is on and working on it hot. If you will go along with this i will tell the man what the problem is and have him start trouble shooting the problem. If not i will keep my mouth shut and say nothing and just let it pass. TURTLE |

Well, it's humming. Gee Wally, do you 'pose we should check the cap? This poster asks : If I turn off the heat (i.e. not on heat or cool), and turn the fan to "on", it just hums (the other furnace works fine and the fan will run). There is a solenoid that clicks, then the humming. Does this somehow give you the impression that he owns a capacitance meter, or knows how to use one ? Or how to check a cap some other way if he doesn't ? From the OP's obvious unfamiliarity with the unit, do you have a great deal of confidence in his ability to tell where the 'hum' is actually coming from ? Gee, could it maybe be a contactor he's hearing ? He needs someone who knows how to fix simple little problems like this to come in and fix it. So blow me.

Good advice, that will help him fix it. I'm Sorry, but Any body can
write that! Flame away if you like, JMO Tony D. Ok, Point Taken. Yup...and thats the best advice you will get on here from any legitimate HVAC technician or contractor. This is Turtle. Tony , Paul give him the correct answer [ may have been blunt ] for if he does not have the ability to trouble shoot a sticking motor. He has no business working on it. Let me put this one on you. I want your wife or girlfriend to come over to my house and trouble shoot a electrical problem on my furnace and your not invited and she will have to work on it alone with no help to tell her what to touch or not to touch while the power is on and working on it hot. If you will go along with this i will tell the man what the problem is and have him start trouble shooting the problem. If not i will keep my mouth shut and say nothing and just let it pass. TURTLE |

Switch off the furnace power. Disconnect the fan belt. Try turning the motor first then the fan drum next by hand. If either device feels stiff then the bearings are seized and you can try fixing the problem if this is what the problem is. The fan axle is designed to run on dry bronze bearings. If oiled or greased the heat quickly boils the oil or grease off. The residue forms a thick crud that grabs the fan axle. The motor may have the same problem. |

If either device feels stiff then the bearings are seized and you can try fixing the problem if this is what the problem is. The fan axle is designed to run on dry bronze bearings. Really? When? Even the old 1950's stuff I work on has oil cups on the bearings... If oiled or greased the heat quickly boils the oil or grease off. Thats a new one...again...if thats the case..name a model of furnace made that uses this... The residue forms a thick crud that grabs the fan axle. The motor may have the same problem. Not if you use the correct oil, like is stated on the units... |

You know - where you spout off all sorts of paragraphs and section numbers from the NEC manual (some of which have nothing to do with the question which shows you are just looking this crap in the book without knowing the meaning - yeah I scanned your messages - needed a good laugh). If you are truly an electrician I pity the fool that hires you. FYI - there are other things that can cause the problem the OP had --- you better do more reading (and no - just looking at the pictures won't do - sorry). It's little wonder why some of the PRO's here on HVAC are so jaded - it's because of idiots like you. |
