This is the genuine OEM replacement kit, part 4450037546, built for the FreshJet 5 Low Profile series and shipped with a fresh mounting strap. It's the cheapest, fastest fix to get your air conditioner starting and blowing cold again.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eWhen your Dometic FreshJet 5 rooftop air conditioner hums but won't kick on, or the fan spins while the compressor sits dead, the start capacitor is the first thing to check. This is the genuine OEM Dometic replacement start capacitor kit for the FreshJet 5 Low Profile air conditioner series, part number 4450037546, and it ships with a fresh mounting strap so you can button everything back up the way it left the factory.\u003c\/p\u003e\n\u003cp\u003eA start capacitor does one job, and it does it every single time the compressor cycles. It stores a jolt of electrical energy and dumps it into the compressor motor to give it the torque it needs to break away and spin up. Over years of hot afternoons and hard starts, that little can wears out. When it fails, you get the classic symptoms: a low hum from the unit, a breaker that trips, warm air instead of cold, or a compressor that tries and gives up. Swapping in a fresh capacitor is often the difference between a dead A\/C and cold air by lunchtime.\u003c\/p\u003e\n\u003cp\u003eBecause this is the genuine Dometic part built for the FreshJet 5 Low Profile series, you don't have to guess at the fit. It's a direct OEM replacement, so the terminal layout and the capacitance match what the unit shipped with. That matters. Get the rating wrong on a generic can off the shelf and you'll be right back on the roof, or worse, chasing a compressor that won't start at all. This kit takes the guesswork out.\u003c\/p\u003e\n\u003cp\u003eThe included mounting strap is a small thing that makes a real difference. On a low-profile rooftop unit everything is packed in tight, and the A\/C takes a lot of road vibration on travel days. A loose capacitor rattling around inside the shroud will chafe its wiring and shorten its life. The strap holds it firm against the chassis the way the original did, so the new part lasts.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Any RV owner running a FreshJet 5 Low Profile unit who wants to keep it going. If you're handy with a screwdriver and a set of spade connectors, this is a job you can knock out yourself in an afternoon. Owners consistently call the capacitor swap one of the easier rooftop A\/C repairs. You pull the outer shroud, find the electrical box, and the capacitor is sitting right there. The hardest part is usually getting up on the roof safely.\u003c\/p\u003e\n\u003cp\u003eA word of caution before you dig in. A capacitor can hold a charge even with the power off, so always disconnect shore power and the battery, then discharge the old capacitor across a resistor or an insulated screwdriver before you touch the terminals. Note which wire goes where before you pull anything, snap a photo with your phone, and transfer the connections one at a time to the new can. Take your time and it's a straightforward fix.\u003c\/p\u003e\n\u003cp\u003eNot sure the capacitor is really the culprit? Here's the quick triage. If the fan runs fine but the compressor won't engage, the start capacitor is the prime suspect. If the whole unit is dead, check your breaker and the thermostat first. And if the capacitor looks swollen, bulged at the top, or is leaking, that's a dead giveaway that it's cooked and needs to come out. A healthy capacitor holds its shape and reads within spec on a multimeter set to the capacitance range.\u003c\/p\u003e\n\u003cp\u003eThis is a genuine Dometic component, not a shelf-stock substitute, so you get the exact spec the FreshJet 5 was engineered around and the peace of mind that comes with it. If your rooftop A\/C has been slow to start, tripping breakers, or blowing warm on a hot day, a fresh start capacitor is the cheapest, fastest thing to try first. Keep a spare in the rig too. They're small, they're inexpensive, and there's never a good day for the air conditioning to quit.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eOEM Dometic start capacitor, part number 4450037546, built to the exact spec the FreshJet 5 shipped with\u003c\/li\u003e\n  \u003cli\u003eFits the Dometic FreshJet 5 Low Profile rooftop air conditioner series for a direct, no-guesswork replacement\u003c\/li\u003e\n  \u003cli\u003eMounting strap included, so the new capacitor sits tight against road vibration the way the original did\u003c\/li\u003e\n  \u003cli\u003eRestores compressor starting torque, curing the classic hum-but-won't-start failure\u003c\/li\u003e\n  \u003cli\u003eGenuine replacement part, not a generic hardware-store can, so the terminal layout and capacitance match\u003c\/li\u003e\n  \u003cli\u003eStraightforward rooftop swap most RV owners can handle with basic hand tools in an afternoon\u003c\/li\u003e\n  \u003cli\u003eA smart spare to keep in the rig, small and inexpensive insurance against a dead A\/C on a hot day\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Dometic reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does a start capacitor do in my FreshJet 5 air conditioner?\u003c\/summary\u003e\n    \u003cp\u003eIt stores and releases a burst of energy that gives the compressor motor the torque it needs to start.
