Perfect for Trane XB80 worked like a charm to start a 17 year old HVAC blower fan motor
Recently bought a home with America Select home warranty and paid about 400$ for one year. Few months after moving in (move in Summer) we had no issues then we turned on the head in October and it worked fine until end of October then one day woke up with no heat. called insurance company they said have to pay decuctable and the HVAC guy came in Johnson HVAC Steelton Harrisburg PA. He spend somewhere between 3.5-5 minutes collected his deductable and said the switch (Safety) and the control board were bad as he was not getting any power to them. Would have to order parts by next wednesday (Trane supply store is in my town and they have the parts - when I checked) then insurance company said they will only cover upto 150$ as I did not have the annual maintanance record from the previous owners. I was looking at about 1000 dollars. Looked at over a dozen videos on youtube and decided to get a transformer 12 $ as no power was coming to the control board. Once transfomer was put, I had power tot he control board. Now I had the inducer motor come on but no gas at the furnace. The board was flashing 4 times indicating a limit switch issue. I ordered that from Trane supply for 22 dollars once that was put in (about 3 minutes to put that in). The ignition lamp came on and gas came on but we had heat. But the furnace was short cycling as the fan was not blowing. It made sense why the limit switch was bad. So stopped the furnace out of precaution to prevent a coil or other big damage and ordered a capacitor. I changed it in 7 minutes and turned on. The sequence of HVAC worked and thank god I had gas and 30 seconds later the fan started like nothing ever happened. I saved a some money and learned to trouble shoot. Thanks for all those that post videos. If I can help please reach out. Best wishes will highly recommend the fast shipping and quality of the product.

Works the same as the OE one for 1/10th the price
Great unit, worked perfectly to fix my air conditioner for 1/10th the cost of the OEM capacitor. I ordered an extra spare to have should it cook a capacitor again.

Got Furnace Fan running quickly.
This capacitor fit my furnace perfectly. I didn't even have to adjust the bracket in my furnace. The capacitor was a direct replacement for old capacitor. It got my furnace fan running. It was a quick and easy install and saved me a bunch of money by installing the capacitor myself.

I know that some of the curiosity ones out there who might be anxious or perhaps excited to challenge the professionals by "take the matter into your own hands by do-it-yourself option" but when you start, may I point out to please be CAUTIOUS as the work involves with -- DANGER HIGH VOLTAGE electrical current that may causes serious injury or death! When you decide to do-it-yourself, before you start, make sure the electricity to the HVAC's unit that you will be working on is completely shut-off...pardon my bla-bla-bla. The GE Capacitor Oval 5 uf MFD 370 Volt 97F5705 (replaces an old GE# Z97F5705, 97F95702, Z97F5702) works with an OEM GE 5KCP39MG B426AS electric motor. The replacement is simple -- remove the old capacitor, unplug the two brown wires, replace this new one, plug the two brown wires back in, close the HVAC unity, testing -- turn on the electricity to the HVAC unit, switch the thermostat to "A/C ON at your desire COOL temperature (i.e., to some people it is between 68F - 72F", at this point the thermostat should trigger the AC unit to power on. If it is, congratulation, you have just repair it; if it is not, the thermostat itself or the motor could be the one that needs replacement. In short, the work can be very elaborate but if ones out there have the patient to troubleshoot, the three common cause for the AC unit to suddenly failed to power up is either the thermostat, the capacitor or the motor (also interchangeably calls the blower) needs repair/replacement. Anyway, greats job, well done Genteq, thank you. P.S. Individuals out there who are still wondering or perhaps not sure where to begin, it is highly recommended to hire the HVAC professionals to take care of your matter as you known that "take matter into your own hands can get worse"...

replacing the simple start capacitor fixed my furnace and saved me a fortune
The heat were not come on in my furnace. I was worried both about having to overpay for a repairman and for the repairman pressuring me to upsell and buy a whole new furnace. with very little investigation when I took off the cover to the furnace I did 10 simple tests or they weren't really tests there were 10 simple things to check that I found from a YouTube video. My furnace pass all 10. so I was staring at it and I noticed this capacitor I figured that must be the start capacitor. start capacitors give the electric motor on your furnace a little jump when you first turn them on because they draw a little bit more electricity until they get running. so I figure it was worth a try why don't I replace this little $10 capacitor and see if my furnace starts. voila $10 later might 28-year-old furnace works perfect. I bought two of these and replace them on both of my furnaces just to be safe and avoid any future similar occurrences with the other furnace.

I bought this capacitor to fix the blower fan in my Trane furnace. The physical size matched the original part, and I used my LCR meter to verify its capacitance rating at 5.035uF. This is impressively close to the 5uF spec, which suggests it's pretty high quality. I expect this replacement will outlast the rest of the furnace.
