HVAC Guys - The Fuse Saver | HVAC Circuit Tester | 3 AMP & 5 AMP Fuses | Fuse Tester for Circuit Breaker - UL Rated 24V AC/DC & 125/250V AC

These work well. If you have an indoor air handler that keeps popping the 3 to 5 amp fuse on the board, this is a great temporary fix. They work well, install easily, and the price is good.

Works great, strong and hard to misplace.

Beats carrying around a pocket full of fuses. It’s a rather have it than not need it than need and not have with this. Lets you troubleshoot and be wrong until you figure it out. Press the reset and try again.

This was an absolute life saver. My AC ent out and after doing some diagnostics I found that the little 3 Amp Blade Fuse had blown, although I could have easily replaced it with a 12v vehicle 3 Amp Fuse, they can blow more often, because they are not made to take to 24v load of A/C. So to buy the right type of fuse was going to cost around $10 but if that blew, then I would be $20 out or more. This was easy to install, just push both terminals into the circuit board where the fuse was located and then push the button to reset. If it ever goes again, just a simple push will get me back up and running, instead of having downtime waiting on Amazon to deliver.

Simple to use just plugs in to the hvac control board blade fuse holder and that's all.. comes with a 3amp and a 5amp mini breaker as well as 3 of each fuse.. saves you all the blown fuses when trying to diagnose a hvac system.
