Thank you for your question do you have a volt meter or a way to verify that the fan motor is getting power from the speed control. if so you will need to check the motor to see if it is getting voltage from the controller to operate. if the motor is getting voltage to run from the speed control and is not running it may be a capacitor. Try to spin the motor by hand with power to it if the motor starts to operate most likely you have a bad capacitor if not and you are getting voltage to the motor then you have a bad motor.

i do have a fluke DVM , but there are 5 wires in the bundle that go to the motor. 3 from the 3- speed switch to the capacitor and 3 from the cap.i wire bundle to motor . I can check for power on one color of the wire bundle to he motor, by rotating the switch control. THe problem is there is not place to put the probe to metal wire, sicne they are protected by the insulation & i dont have the "needle type " on my DVM.how do i test the Cap? its really big and a square shape. but most important, i need a part number of it to Order a new one, thats what i contacted & paying for with this inquiry! There is no wire diagram on the web for this Honeywell air filter to outsiders .... only repair tech like yourself have access to speacial data bases that have this .the 2nd questio is where do i get a cap like this . ? or a motor???

You can check capacitance using the NF setting on your meter if it is capable. What is the model of your fluke so I can check if it has the capabilities of checking a capacitor? Also to check voltage on the wire you could use a razor knife and bare a small portion of wire, just make sure you use electrical tape to wrap the wire back up after testing.

Graingers will be able to match either the capacitor or the motor if you have have one were you are located. You could also send me a picture of the motor data label and i could try and locate one for you online or direct ship it to you with a premium service.

im not at the bench right now , but i will be in a couple hours , can i reply with the FLUKE model then? Im 99% sure it does NOT have capacitance testing .. but ill tell you the model. ITs 25 yrs old , but works great . IM going to get some additinal test leads on ebay now, so ill have the alligator , and needle piercing capability in future . are the hook " variety worthy of owning too?I will take a picture of the sq CAP. as well as the motor, ... what number should i fwd them too??
HVAC Technician: Chad DeYoung,

Sounds like your meter will most likely not be able to check capacitance, but you can try and spin the motor while it is trying to run, if the capacitor is the issue the motor will likely start running so watch your fingers. Check it on all 3 speeds you may have lost a speed as well as the capacitor. One last thing I am not sure how much this humidifier costs but unless you really want to fix it, it maybe an option just to replace the whole thing.

But I can try and help you out the best I can from the PC.

We can do a premium service and you can send me your number and I will respond to you with my info.

Grainger stocks or can get just about any motor you need I use them for my company when I have a motor that is not standard. They can cross any motor or you can through their website. If you find the motor or a cross and dont like the price I can certainly see if I can get it cheaper for you. You can just PM me those pics if you would like.

I would say your issue is in the speed control the motor or the cap.

hi CHadi found the model of my FLUKE DVM is a 73. I dont think it has capacitance testing ability , .i took some pictures of the motor and will email them , what your email address ?
Customer reply replied 11 months ago
i checked the motor by handspinning while i cycled thru switchs ... no luck .. still dead.
HVAC Technician: Chad DeYoung,
 replied 11 months ago

not the capacitor then, I would definately be suspicious of the motor. If you can check the motor for voltage after the peed control. If you are getting power to the motor and it is not operating then it needs to be replaced.
