1. Install a 30 amp auto reset Circuit breaker. CHEAPER than replacing fuses.
2. I(F you are positive that the ONLY item on that 30 amp fuse is the landing gear, then the motor is probably defective. IF you have other 12 volt items on that fuse then the accumulated amp draw may be blowing the 30 amp fuse. Doug

The only problem with auto reset circuit breakers is that some designs will weld the tips and take out the harness. I'm speaking of the clicker style that is basically a metal arm that heats up and pops open. When a fault occurs and they sit and cycle over and over and can end up welding the tips. Just mentioning it. The only breaker I would use would be a manual reset. If it pops maybe it's a one time thing, if it does it again find the problem.

Well, I have 36 years of working with and seeing Auto reset Circuit breakers in action. NEVER had a problem with what you state. Possible? Yes, but never had it happen where the Auto CB welded closed and that caused a burned harness. Doug

I know. I spent 40 plus years on lift trucks etc and seen them used in many areas. Normally they fail open but maybe the ones we had trouble with were from you know where. We had a fleet of cheesy Motrec personnel carriers that the drivers kept taking the fuses out of to prevent others from using them. One of our guys had the idea of wiring in auto reset breakers. Problem solved until they had a solenoid or or component fail. Then the breaker sat there and clicked on and off until it welded and smoked the harness. It was in more recent years so it's probably like the propane regulators and other junk that we are getting. We were constantly complaining to management to order oem potentiometers and other components as the failure rate was very high. But but....they were saving money! I'm sure you know that story.
