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 two year limited replacement policy. If this part fails within two years from date of purchase, return the defective part and a copy of the original invoice to the place of purchase for replacement.
