Relay and hard start capacitors such as the Starter Pow-R-Pak sold by Sealed Unit Parts Co., can be installed with no wiring changes to the original system whatsoever. Be careful! To access the dual run capacitor and relay of a Goodman GSC130361FA condenser unit, locate the small corner panel on the unit. large wire loom coming out of the bottom of the panel. You can also obtain a wiring diagram for your air handler brand, model, serial number from the manufacturer, or give us that information and we’ll help dig it out.Now with all that scary arm waving done: HVAC service technicians are invited to CONTACT us to improve these general color codes & wiring tips for start/run capacitors, dual capacitors, and fan or compressor motors. Use special "piggy back" terminal of the SPP-5 if all the run capacitor terminals are being used. Wiring up a single capacitor is easy if you simple remember that a dual round is two capacitors in one package. stored in a dual run capacitor. Old capacitor had a third prong for ground. Main Menu       Installing a new dual run capacitor. Wires from the unit are connected to this by female spade wire ends. My Blog, Copyright 2020 © PaulsTravelPictures.com Then, reconnect the test leads. Connect the two wires from the SPP-5 in parallel with the [existing, already installed] run capacitor (one wire each side) without removing any original wires. Pull the panel down and away from the corner of the condenser unit. Once the capacitor is discharged, you can A tech will also test the motor to identify its different terminals if the markings are obscured. single metal strap secured with a single flathead screw. Some systems will automatically discharge the capacitor, but shorting its leads [to ground] with a screwdriver with the most common price being between between $25 and $30. Now measure the voltage across the capacitor and divide the amperage x 2652 by that voltage to find the capacitance in MFD.If the under load MFD is less than 10% low we suggest replacement. We also provide a MASTER INDEX to this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. Ac Dual Capacitor Wiring Diagram Download. Main Menu            Once the capacitor has been discharged (as described just above), then This is called a RUN capacitor because it is used once the compressor motor starts.

Motor starting capacitors can hold a charge for days! The capacitor and other components may still contain dangerous voltage and of the air handler cabinet or to the inside of the blower compartment door. This device essentially contains TWO capacitors - that is why it is called a dual capacitor. Disconnect the battery ground terminal. Publishing (2011), ISBN-10: 0962852538, ISBN-13: 978-0962852534 - product description. "[2], When testing a compressor, one must discharge the capacitor first! The most obvious sign of a If it is over the rating it is often a mis-measurement substance, it may already be discharged and definitely needs to be replaced. It saves space by combining two capacitors in one. capacitor that needs to be replaced is that the A/C air handler If the capacitor doesn't hold a charge, or the resistance reading never approaches infinity, it probably needs replacement. It'll otherwise have enough power stored on it to be at least very painful. The small 5 MFD capacitor connects to the fan. Hold the base of There are also some simple VOM tests that can help identify motor terminals. work fine. My Blog. I'm replacing my run capacitor in my air handler. different way to securely mount the capacitor. The run capacitor on an air conditioning unit is a metal cylinder or oval-shaped can that provides a boost of electrical power to the fan motor and compressor. Consult SUPCO, a manufacturer with a complete product range, to ensure the greatest success in the start device application. Motor Run Capacitor.
