About this fuse

The Allied Innovations 3 Amp Slo Blo Fuse (229-003) is a critical safety component designed for spa electrical systems that require reliable overcurrent protection. This AG-type slow-blow fuse provides 3-amp protection for sensitive electronic components in your spa's control system, allowing temporary current surges while protecting against sustained overloads that could damage expensive circuit boards or pumps.

Built to Allied Innovations' OEM specifications, this replacement fuse delivers the exact fit guaranteed performance your spa needs to operate safely and efficiently. We ship same-day from our Canadian warehouse and back every fuse with our comprehensive 1-year warranty for complete peace of mind. The slow-blow design prevents nuisance tripping during normal startup cycles while maintaining essential circuit protection. Always verify amperage requirements match your spa's electrical specifications before installation, and replace fuses only when power is completely disconnected.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

Spa control panel completely dead with no display
Spa powers off unexpectedly and won't restart
Specific spa function (lights, blower, ozone) stops working entirely
Circuit board shows no power after a surge or short event
Spa was recently serviced and now a function is unresponsive

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

Confirm the blown fuse on your board is rated 3A — check the fuse body or board silkscreen label for amperage marking
Confirm the fuse type is AG (glass tube, also called AGC or 3AG) before ordering — verify physical dimensions match
Never upsize the amperage to 'fix' repeated blowing — a fuse that keeps blowing signals an underlying fault that needs diagnosis first
Inspect the fuse holder clips for corrosion or heat damage — a damaged holder should be replaced at the same time
Disconnect all power to the spa at the breaker before touching any fuse or board component

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
