This is a direct-fit 1 amp replacement fuse for PolarCool evaporative coolers. If your unit's fan or controls have stopped responding, a blown fuse is one of the first things to check, and this is the exact part you swap in.
This 1 amp fuse (Part No. 3010-2999) is built to sit inline with the control board on PolarCool evaporative coolers, giving the electronics a defined failure point before a surge or short can damage more expensive components. It's a low-cost part, but it does a specific job: protecting circuits that are otherwise expensive to replace. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fitment & Requirements
- Fuse rating: 1 Amp — matches the original PolarCool control board fuse spec.
- Fits PolarCool 18", 24", and 36" evaporative coolers, including Zone and PRO series units.
- Does NOT have confirmed fitment for PolarCool models outside the 18", 24", and 36" Zone/PRO lineup [NEEDS VERIFICATION].
- Function is limited to overcurrent protection of the control board and electronic circuits — it is not a substitute for a capacitor, relay, or motor overload protector.
A fuse that blows repeatedly is telling you something — swapping it again without checking the circuit is the technical friction most techs run into on service calls. Before you seat a new 1 amp fuse, inspect the old one for a broken filament or discoloration, and check the fan motor and wiring for a short. Replacing a fuse without correcting an underlying overload just burns through your spares and risks recurring downtime for the customer. Follow lockout/tagout procedure and disconnect power before opening the fuse holder — this is standard practice for any live electrical component per OSHA/NEC electrical safety guidelines. Once the new fuse is seated securely in the holder, restore power and test fan operation before closing up the unit.
Key Benefits
- Direct-fit replacement — no modification needed for installation.
- Protects control board and electronic circuits from surge and overload damage.
- Restores fan function quickly, minimizing cooling downtime.
- Low-cost part that's worth stocking in multiples for troubleshooting and maintenance inventory.
- Compatible across the 18", 24", and 36" PolarCool Zone and PRO series lineup.

| Repeat Failure | If the new fuse blows again, investigate the electrical fault before installing another. |
FAQ
Which PolarCool coolers does this fuse fit?
It's a direct-fit replacement for PolarCool 18-inch, 24-inch, and 36-inch models, including the Zone and PRO series.
What is the amp rating of this fuse?
It is rated at 1 Amp, designed to provide overcurrent protection for the control board and electronic circuits.
What does this fuse protect against?
It protects the control board and electronic components from damage caused by electrical surges, shorts, and overloads.
Should I buy more than one fuse?
Yes. If you're troubleshooting an electrical issue, keeping a few spares on hand speeds up diagnosis and gets your cooler back online faster.
What do I do if the replacement fuse blows again right away?
Stop and investigate the underlying electrical fault before installing another fuse. A repeat blow points to a short or overload elsewhere in the circuit, not a bad fuse.
