York Furnace - Fan Doesn't Spin on Heat

Hello,

I have a York furnace 90% that has had a lot of issues over the years. I've replaced a pressure switch, 3 inducers, and a fan motor. I have an issue now when I turn the heat on at the tstat the inducer kicks on, gas lights, and I hear the fan motor try and kick on but it won't spin. If I turn the heat switch off and turn the fan from Auto to On the fan turns. I can then turn the tstat to heat and the fan will turn off, inducer turns on, furnace lights, and the fan starts spinning.

So basically if the fan is in Auto and the t-stat is turned to heat the fan will not kick in but there is power sent to the fan motor. I did some research and there was mention on a relay on the control board that might be faulty. I replaced
The control board but it's doing the same thing. I'm not sure what is left except for the capacitor?? Thanks

Welcome to the forums!! To better assist you please post the model number of your furnace. It may be a bad run capacitor. With power off to the furnace inspect the capacitor to see if the top is bulged. A bulged top is an indicator (but not always) the capacitor is bad. The capacitor can be tested with a voltmeter that has a capacitance test function to see if it is within specs listed on the label. Most DIYers replace the capacitor because it is relatively cheap and pretty easy to obtain.

Thanks for the reply. The model # is GY9S080C16DH11G. Guess I'll check the run capacitor next. On this particular model it's a pain to get to the fan.

Here is a link to the installation and parts manuals in case you don't have them:

It looks like the blower run capacitor is an oval 10uf 370VAC.

If the parts diagram is accurate it looks like the run capacitor is readily accessible (circled in red on attached diagram).

Thanks for the links. Wish I had purchased one when I purchased the board. Starting to get kinda cold here, wish I could find one local rather than online and waiting a few days for it to show up

Do you have a local Grainger's? They will have the capacitor you need on the shelf. Any oval 10uf 370VAC (verify this from the existing) will work. Here is one example that will work:

Some locations are flexible with the policy of selling only to pros. I have been in one of the local stores many times when a person comes in and purchases items under the account "cash". Never seen a person questioned yet. Another method that works is to establish an online account and select "will call". Then you go to the store you selected to pick it up in person. That seems to work also

Thanks Firedawgsatx. I got the capacitor ordered last night and went down and picked up this morning. Installed it and everything appears to be working. Turned the heat on and the fan motor started with no issues. Thanks gain for the links diagrams.
