Best Hvac Capacitor For Lennox System

This capacitor is the direct replacement for many furnaces, air conditioners, and heat pumps. This model will replace all 1-1/4″ x 2″ oval base capacitors rated at 7.5 UF (5 MFD) for 370 volt applications. This item is made in USA to exact tolerances. IMPORTANT NOTE ON CAPACITOR FITMENT: This is an oval capacitor which measures 1-1/4″ x 2″ at the base. Due to changes in capacitor materials and manufacturing over the years there have been slight variations in case diameter. This is especially true if replacing an older plastic capacitor with a new metal case capacitor. If your capacitor mounts through a hole bracket it may be necessary to enlarge the hole slightly with a file or grinder on some older units. This part is covered by the exclusive OneTrip Parts five year limited replacement policy. If this part fails within five years from date of purchase, return the defective part and a copy of the original invoice to the place of purchase for replacement. Contact the authorized OneTrip Parts dealer that you purchased the part from for details. Original equipment manufacturer’s brand name(s) and part numbers are used for identification purposes only. This item is supplied by OneTrip Parts and meets or exceeds original equipment specifications.

This capacitor is the direct replacement for many air conditioners and heat pumps. This model will replace all 2-1/2″ round capacitors rated at 60+5 UF for both 370 and 440 volt applications. This item is made in USA to exact tolerances. IMPORTANT NOTE ON CAPACITOR FITMENT: This is a round capacitor which measures 2-1/2” in diameter at the base. If your capacitor measures 2” in diameter at the base, this IS NOT the correct capacitor for your unit. Due to changes in capacitor materials and manufacturing over the years there have been slight variations in case diameter. This is especially true if replacing an older plastic capacitor with a new metal case capacitor.

A capacitor is an electric component that temporarily stores an electrical charge. A dual “run capacitor” supports two electric motors, such as a fan motor and a compressor. Round dual run capacitors are used to start and run the unit more efficient. It saves space by combining two physical capacitors into one case. The dual capacitor has three terminals labeled “C”, “FAN”, and “HERM”, which stand for the *C*ommon, Fan, and *HERM*etically sealed compressor.

Dual capacitors come in a variety of sizes, depending on the capacitance (µF = MFD = micro farad), such as 60 plus 5 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt. It will work for a while and will fail prematurely, as exceeding the capacitor’s rated voltage will cause the dielectric to break down and the capacitor to short out. Same as an electric wire- 600V rated wire is better than 300V one .The capacitance(µF or MFD or micro farad) must be the same or stay within 10%+ or 5%- of its original value . Example: 60 µF cap can be substituted by 57 – 66 MFD with the same or better voltage ratings capacitor.

If your fan is working but compressor not, or the capacitor is bulged on top most likely your capacitor is defective. Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs.

You will ask “Why I need a Cap that is rated 440V in my A/C?”

Answer: You need to realize that a motor is an inductive device. When the supply voltage is applied to the motor run winding, the voltage across the start winding will be increased to a higher voltage value. A motor acts like a transformer with the run winding acting as the primary and the start winding acting as the secondary. This is why the capacitor has a much higher voltage rating than the 230 being the supply voltage.

If a Capacitor is not EIA-456-A approved means it is NOT approved for USA market.
