Great value, easy to install
Works great, easy to install, but be sure you safely discharge the capacitor before you remove your old one. Lots of great you-tube videos on how to do it. Great value!

Cheap Insurance
Having this capacitor on hand saved me hundreds of $$. When my outdoor AC compressor fan was buzzing, a quick change of the fan capacitor fixed the issue. Total time was 20 minutes start to finish. Glad I had an extra on hand.

Problème de démarrage réglé
Je devais pousser les palettes du moteur pour qu'il démarre. Un huilage des roulements n'a pas fonctionné longtemps, mais le remplacement du condensateur de démarrage sur le ventilateur a réglé définitivement ce problème. Pièce identique à celle en place sur thermopompe Hayward.
