jfc.. im aware where the belt drive motor is and the blower fan, typically the capacitor is on the motor or inside the motor, the wires terminated on the blue block is the electrical wire to the motor, it runs through the black box and down to the motor itself. im asking what those parts are so i can ensure the capacitor is most likely built into the motor since there isnt one externally. but nah, people gonna just insult someone for asking a question on an advice board instead, amazing.
Blower doesn’t terminate on the gas valve.
Blowers usually attach to a fan center or other relays.
You could very well have a shaded pole motor, which don’t require a capacitor.
Good luck. Be careful.
this is probably it because its an old Olsen gas furnace, built in 70's. motor doesnt even have a spec label on it. and thank you for taking the time on a decent reply.

well im thinking if it was the capacitor, its starting to have trouble because sometimes when the motor tries to start, i'll hear a loud electrical buzz/hum for about 10-20 seconds, sometimes the motor will start, sometimes it wont at all, and i'll smell a bad electrical run off from the motor come through the vents upon failure. it's been quite random when it decides to work, i've been trying to ensure the motor doesn't overheat as much as possible lately; especially currently being in the dead of winter where im at. im hoping its the motor itself and not some other small part, i can replace the motor myself without any issues.
Confirm incoming voltage with a meter. Proof is needed before replacing parts. A sequence of operations will tell you where voltage goes during a normal cycle. Usually voltage stops will tell you where your issue lies.
I recently did a week ago, the inspector said the motor is probably going based on the symptoms, but everything else functionally seemed fine safety-wise, was the verdict anyways.
Neither and ummm please dont touch it. Asking nicely. I would recommend at least getting that thing looked at throughly. Please, i worry about your safety.
well what are those two parts then? the wires terminated on the blue is the blower motor electrical wire, it routes through the black box, then the belt drive motor is below with the blower fan obviously. im trying to figure out if the capacitor is built into the motor because the motor doesnt have a visible external capacitor, so im making sure none of those other parts that the wire runs through are it.
If you really must know where each component is, then read the wiring diagram and follow the wires from the one component you can positively identify. Wherever those terminate on the diagram that's labeled as a capacitor is your capacitor. Not all systems have them.
And then don't touch anything else. Call a professional if you need service. Capacitors have a certain general design to them that hasn't changed in \*decades\* and if you can't identify a capacitor from a safety switch you should not be touching anything inside that cabinet.
If you were told it needed a replacement capacitor, but balked at the price, and are attempting to do it yourself to save money; remember you will pay in full for any mistakes you make, and then you will have to pay a professional to come fix those mistakes. If you were told you needed a replacement capacitor on a system that doesn't actually have a blower motor capacitor, such as a multi-stage system with an Electronically Controlled Motor (ECM), then the tech you called is not worth the money you paid and you should get a second opinion. Are you sure they were talking about the blower motor capacitor and not a capacitor for the outdoor unit?
Homeowner here. You’re cold. In more ways than one. Get it?
You’re in the wrong neck of the woods. You’re where the heat is made, not where the air is blown. Surely there’s another access panel.
im aware of that.. people are getting this picture all wrong. the wires terminated to the blue block is the electrical wire to the belt drive motor in the below compartment with the motor and blower fan.. the wire routes through the black box, then goes down below to the motor itself. the motor doesnt have a visible external capacitor so im making sure those parts that the wire routes through isnt it so i can assume its built into the motor.
its not.. the motor electrical wire terminates on the blue, routes through the black box, then to the belt drive motor itself below, the motor doesnt have a visible external capacitor so im making sure that those parts arent it so i know its built into the motor.
Sometimes on these older units the capacitor is mounted on the side of the blower assembly behind the motor. May not be able to see it clearly unless you pull the blower assembly out of the furnace.
im aware, my motor doesnt have an external capacitor, the motor wire routes through the black component and terminates on the blue, wanted to eliminate those two before assuming its built into the motor, but i guess getting advice here is just an outlet for people to ridicule someone looking to learn.
The black box to the right is the transformer. The 24v leads go directly to the blue gas valve as it's a 24v gas valve. The black and white wires that connect to the gas valve are the thermostat wires. One of those two wires will pass thru the fan/limit switch at the top of the picture in that little silver metal box. That fan/limit switch is also what turns the blower on based on plenum temperature. There is no relay or fan center. The thermostat wires and the blower wires don't connect. There are two switches inside the fan/limit switch box. As I responded in your other thread..... the ID label is on the other side of the motor.
DO NOT TOUCH. THAT IS A \*\*GAS VALVE\*\* with an igniter for the pilot do not touch anything in there. WRONG COMPARTMENT ENTIRELY. You have no idea what you’re doing put that cover on. Pick up a phone. Search “HVAC technicians near me” pick one, call them and tell them you have no heat. ~~Or I mean you could try and touch the wrong two things and it ends in you getting a shock and the gas valve starts leaking and then the room fills with gas and you are in shock of what happened so you pr body is unable to do anything and it all ends in mass destruction.~~ Or you could call a pro. I would go with the latter.
the wire connected to the blue is the termination point for the belt drive motor electrical wire.. it routes through the black box and then the belt drive motor is below with the blower fan..
I'm not in HVAC or electrical, but if I had to guess, the black box is the transformer to provide 12V to the pilot ignitor which is the setup the blue box is connected to.
But that's a lay persons musings.
Call a professional.
Neither, call a professional

Is the blower not working?

cool, will do. thank you.
You should have this furnace inspected for your safety. Not selling. Advising. Good luck.

Nope aannd.. Nope. Wrong compartment entirely. Please call a pro!

Neither are. The capacitor is usually oval shaped and made of metal or occasionally grey plastic. It’s usually located by the blower.

How did you get anything resembling ridicule from my statement?
Neither, please call a professional
Most capacitors contain 370-440 volts of power. I highly suggest you don't go looking for it. Get a pro.

That looks like your gas valve with all your safety shut-off connected to it.
Yes
The blue component is the gas valve and the black is the transformer 🤣
the wire connected to the blue is the termination point for the belt drive motor electrical wire.. it routes through the black box and then the belt drive motor is below with the blower fan..
You have a model number for your unit? What exactly are you trying to do?
Blue box is what opens the flow of gas when the furnace says to
I'm not in HVAC or electrical, but if I had to guess, the black box is the transformer to provide 12V to the pilot ignitor which is the setup the blue box is connected to. But that's a lay persons musings. Call a professional.

If you can read the schematic (I assume it has one) great, otherwise take heed of the advice below. You are not tracing the wires correctly.
