GEGenteq Round Capacitor 70 7.5 uf MFD 370 Volt 27L556BZ3 27L556

It replaced my original OEM part (after 11 years service) and worked perfectly. Highly recommended.

Came home from work last night - house was 82 degrees. Initially thought it was the thermostat, traced problem to external compressor. Compressor was running, fan was not. Could manually start fan up using a stick to start it spinning counterclockwise. Determined that the capacitor was bad. Visual inspection revealed castor oil leaking from rusted top of motor start capacitor. Needed item is not in stock at big box stores, any Grainger in Houston. Amazon had next day delivery. Item arrived this afternoon. Brand New, in good condition but no wiring instructions. The top has three connectors: HERM, FAN, C (for common). Some googling indicated that HERM is for the compressor wire, FAN is for the fan and C is for both legs of the 240 V power in. On a 1.5 ton residential Goodman: HERM connected to the brown wire, FAN was the yellow wire, and C were the red and purple wires. This may be different for your AC unit, so doublecheck before connecting things incorrectly. Also, the reason these are not sold to the general public is that you can electrocute yourself very easily. Above or near your AC unit, there will be a disconnect box with disconnect switch in it . Make sure that this switch is disengaged before touching the capacitor. Also make sure that your power is shut down at the circuit breaker box in your house. Apparently people bypass the disconnect switch for whatever reason and if you don't shut down the mains at the circuit breaker, you could still have power going into the capacitor and electrocute yourself and die right there. I also shorted the connectors on the old capacitor to make sure it was discharged prior to handling it. I used a screwdriver with a well insulated handle. Once I verified that the capacitor was discharged, removing, replacing, rewiring (pushing the lugs back on the connector tabs of the new capacitor) took all of 10 minutes. I fired it back up and it works now. 15 minutes of work saved me a probably expensive repair call. Thank you.

I was able to diagnose my AC problem and fix it myself, saving hundreds!

Replacement

This is not about the product. It works great. So does my central AC thank God. This review is about Amazon and their great business model and inventory that allow me to escape 101 degree hot weather with there quick overnight delivery service. All this for a $25 part. Life is good! The day before I went to 3 local HVAC distributors and came up empty.Thanks Amazon. You got my 5 star vote.

Good value

I heard the capacitor is the most common failure item for heat pumps and air conditioning systems for homeowners. After an acquaintance had their 15-year-old AC unit fail with a blown-out capacitor ($280 service call), I took a proactive approach and replaced the capacitor in my 15 year old heat pump before the heating season. This one is the same size and has same specifications as the old one. Very easy to replace.

If you have ever experienced the lovely HVAC business model of a correlation between your discomfort in the hot summer and the high price they charge for their services, then you will know that swapping out a capacitor can be an easy DIY that can avoid the price gouging that seems to be standard operating procedure for that entire industry. I admit that there may be other issues that should be looked at, such as refrigerant level, and other maintenance items, and it’s perhaps not super safe to mess around with these capacitors, but I just thought as a first step, while awaiting the availability of a local HVAC company to see if changing out the capacitor could be the solution… it was, it maybe took 20 minutes to swap out, and I am very pleased. Amazon should get high marks here for making a product that used to be difficult to get a lot more accessible and convenient for anyone! Thank you Amazon!!
