Blower Quit Working

8 posts in this topic

Winterizing my 256 this weekend, had the engine running with the blower while I fogged the engine. Shut everything down, waited a while, then changed the fuel filters. Lot of gas fumes so I figured I'd flip on the blower just to help clear out any fumes down in the bilge. Now the blower won't run!! The light on the switch comes on but nothing! Checked the breaker and it's not tripped. Any ideas?

First check the blower switch itself. A wire may have come loose. The light is separate from the blower feed. If they're OK, check your wiring connections. You may have stepped on one while working in the engine bay, pulling it apart. If they're all OK, disconnect the vent hose at the blower. With the switch OFF, see if the fan blade will turn. Check if any debris got sucked up into it. If that's all clear, try disconnecting the positive wire leading to the blower and connecting it directly to the positive side of the battery. If it now works, check the blower switch. If it doesn't, your blower motor went. My first guess is a disconnected wire, either at the switch or the blower (blower more likely). My second guess is debris in the blower itself. Good luck and let us know what you find. Hy

Do you have an auto fire extinguisher mounted in the engine bay?

If so, Try checking the connections to the fire extinguisher if the wire is loose or disconnected it will not allow the blowers to run.

Oh, that's good info! I had unscrewed the bracket and moved the tank in order to gain better access to the bilge. I may have knocked the wires loose? Thanks!

Toddler: Thanks for the info. I didn't know that the blower circuit was in series with the built-in fire extinguisher. I had never had a boat with a built-in extinguisher before the present one and I do not have a manual for the extinguisher system. I'll keep that info in mind for future reference. Hy

If you have the blowers on and you have a fire in there. It will suck air in making it worse and suck the powder out; which in turn doesn't do any good either.

Don't thank me thank the "Forum" who told me about it.

It seems like I was told that these motors have a thermal cut-off (like when you run them too long). just a thought....good luck

Thanks for the tip--that's what it was. Took me 2 minutes to find the wire that was disconnected from the fire extinguisher.
