2005 - 340 DA Exhaust fan question

[gwkiwi]

I am trying to find my exhaust fan for the kitchen / bathroom on my 340.

Sea Ray wasnt much help as the fan is not shown in the manuals just listed as a replacement part.

I removed the fridge today and can't determine if this unit (see photo) is the fan or part of the AC system.

Any ideas what the box is I want to make sure because it is not easy to remove ?

That is your AC/Heat duct work. It is wrapped in insulation to prevent sweating. The box is the bi-directional diveter for air flow. When it splits behind the fridge, one part goes to the head the other goes to the aft cabin outlet. There is another "box" behind the v-berth TV which splits the air flow from the AC under the v-berth mattress to the port side v-berth vent and then back towards the vent you are looking at. All of that airflow comes off of the one side of the AC unit. The other side goes to the main cabin. PM me if you need any more info as I have replaced alot of that duct work due to restrictive airflow.

That's what I thought but I really appreciate your confirmation, I guess my next step is to remove the microwave and see if the blower unit is tucked up behind there.

Thanks again

Gerald, maybe check behind the microwave. I said that because on my 04', when I turn that rocker switch on right under the microwave, the fan sounds seem to come from behind there. Good luck.

P.S. I just looked in my parts manual and they don't show it in there either.

Or, since you pulled the fridge out, see if you can see that vent cover that is located on the port side of the hull and follow that back to the actual blower.

Gerald--
Noticed you have a dinghy on back of your boat. I'm looking at davits now (e.g., Hurley; Nautley; etc). Which one do you use, and are you happy? Any advice one way or the other on using davits on high swim platform of a 340?:huh:

Gerald are you still in the palm beach area? sometimes just a few swiches have to be turned on to get it to work if your still here pm me and i'll run over and take a look

This exhaust fan and motor is behind the microwave on my 2001 310DA. Real easy to get to. I thought it would be a real problem to repair as it stopped working and the circuit breaker kept popping off. I just reached into the fan and spun it around a couple of times. Appeared to be just dust accumulation. Put it back together and it's been fine for two seasons now. Hope this helps.

Well its now early March and I decided to fix the mystery fan blower once and for all.

Sea Ray emailed me back on Friday and told me the blower fan for the bathroom and kitchen is located in the rear berth port side cabinets.

It made sense so on Saturday morning I started disassembling the interior shelves of the cabinet and took out the rear panel. I also made sure the AC / DC charger was off at the breaker as the fan was only a couple of feet from there.

After putting a light into the area I wondered how the heck I was going to get in there to do the change over.

After squeezing in rolling over, dropping the light on my head, and other delightful things I had the fan unscrewed from the hull, wires snipped and took off the hose attachment and squeezed back out.

Being down here in Key West I didnt know how long it would take to find a new fan but a local marine hardware store had the exact fan in stock I couldn't believe it and seeing that I had priced one a couple of months ago their price was very fair.

Now to put the little bugger back in, after more scrapes bruises and a couple of "oh goshes" the fan was in place, wired in and all put back together.

The final step was the test and it all worked as it should with good suction at the vents and good push at the exhaust.

Here is a picture for those of you if you have to replace your fan. Sorry about the picture it was taken with my blackberry under the shelf where it was hard to get a good picture.

Realize this was a while back, but how did you get the cabinet disassembled? I took a look in there yesterday chasing the same inop fan but saw no screws or fittings to go after in the cabinet. Thanks!

Gerald on my '05 340, at the end of the mid-cabin berth on the port side, was a shelf unit. If you open the doors, remove the shelving and the back wall (about 6 screws), I accessed mine that way. I could just reach it as it is forward of the opening that you will expose by removing the interior walls of that shelf unit. It is mounted against the hull...

Thanks, Very helpful. To access the SDA 340 galley and head blower fan vent motor, enter the mid cabin port cabinet, and remove the shelving (6 screws) and back panel (4 screws). It is up to the right connected to the hull directly inside the forward of the two outboard vents on the port side. The rear vent is for my central vacuum. My fan was inop and started to run after I gave it a few knocks. It’s like something had gotten caught up in the fan and got loosened. Ten minutes to open the panel, two hours of yoga to replace, so I did not replace. If I need to knock it again, I’ll do from the outside as the fan is right up to the vent. Pics attached.

Great pics Sir! And I forgot to mention that is where the battery charger is located also!

Question for those of us that are "yoga challenged". Is there a way to get the fan replaced without climbing in?

Hi Robert. I can't image short of incredible structural removal that there's any other way in. I recently had to replace mine after the temporary un-seizing I wrote about up above. It's not too bad the way I figured it out. It is work done on your back with your arms up. I built a platform using a somewhat full liquor box (it was the right height) set through the removed cabinet back and into the compartment. I used that to hold up the removed back of the cabinet as a bridge through the opened cabinet into the compartment. (I had that sitting on a blanket to avoid any scratching.) That become an easy slide in/out surface to work with my hands over my head. (Think of a car mechanic under a car on flat dolly.) I put a pillow at the head against the bulkhead and that kept my head elevated and comfortable. Once in, you'll remove the two taped on ducts from the galley and head from the vent motor. Cut the electrical wires (after closing the DC vent breaker of course). Removing the vent means loosening 4 or 5 screws. The two on the side you're approaching from have to be removed, and the vent slides out from under the others. I reused the vent duct splitter from the bad unit and attached it to the new unit. Then used duct tape to seal. I had to add wire to the leads on the new vent motor as they were short. (I forget the gauge, but the requirement is in the replacement instructions.) Then secured it back up against the bulkhead reinserting/tightening the screws. I taped on the ducts (hardest thing I did, getting the tape around the back of the ducts without it sticking to itself). Finally, I attached the wires.

eauty - Did you find restrictions? Ours doesn't seem to have the flow that many other boats have. What did you do to improve yours? Thanks, Korkie
