There is another oil port on the front of the motor Byron...If you don't oil that one too you are wasting your time...

It only takes 4 slot head screws to remove that whole motor/fan/cage assembly on the EFB models...

Hi Steve. The motor was/is dragging a bit. Did get some oil in the port in the back. Will run as much as possible to see if it loosens up. Have adjusted speed adjustment all the way counter clockwise the back about 3/4 turn. motor does not lioke to turn slow.

Hmmm...Thought I answered this...Maybe forgot to hit the post button ???

 

Anyway I asked: When you say "Seems restricted a bit"... What do you mean ?

Is the motor stiff to turn, or are you referring to a lack of air flow ?

 

If the latter...That's just the nature of that old Blow-Thru EFB-6...They never did move much air even when new...

But your's could also be plugged up on the back side too...Take a flashlight and look at the coils/fins behind the fan blade...

Most never got washed out because it required removing the fan assembly (only 4 slotted screws to remove the whole cage & motor)

The exact same motor is no longer available from Dometic and the last one I changed out was a split capacitor type (original was shaded pole) that when finished didn't like to slow down much...

Are fan motors available for the old EFB - 6. Mine seems to be  restricted a bit. There also seems to be an oil port in the back. I will run it some more and adjust the speed control behind the red sticker.

 

Thanks again.

Steve,

Doing a similar project on a 1980 Hatt, 53MY.  Going from 3 knob mechanicals to FX1.  Hope you don't mind a question… I have hooked up 2 of the 5 units on the boat.  I hooked up the main salon unit – all is good.  I hooked up the master stateroom unit and at first it works fine.  But when I go to turn it into "away" mode or "off", the water pump never turns off (almost like the trigger is stuck in the on position).  Thought I might need a resistor for voltage leak, I tried a 23k and a 36k resistor at the pump relay box in the ER, but that didn't do it either. So I flipped that unit's box out with another one I have (new for another unit) and the same thing happened.  Worked fine initially, then pump stays on continuously when I go to turn it "off" or "away".  Wondering if you may have run into this.  I have a couple of newer Triac's and triggers that I have upgraded to in the ER room, and am not sure if the master stateroom has a new one or old (something to check out next time at the boat).  I talked to tech support at Coastal Climate and they suggested testing by removing the pump wire from the terminal switch – not sure what that will tell me other than if its hooked up correctly (it is).  Any ideas?

If your new 3 knob has fan speed...Then cut out the resistor on the back of the EFB 6 & run the fan wire from the control, directly to one of the fan motor wires...The other fan motor wire goes to neutral.

There will be a screw hole in/on the fan speed control (under a red sticker) that if you use a very small flat blade screwdriver you can feel the slot in the pot & adjust how low is low fan (with the knob at full counterclockwise)

If you set it too low the coil might ice up when the cabin gets colder...If it does, then just go back in & raise it up a bit.

Just got back from boat and hooked up new control. The fan unit is a EFB-6.  It has the white, orange, yellow and brown 18 ga wire going to it. I hooked up the orange and got hi speed the the knob on high. No fan speed control. It has resistors mounted to the fan assembly. What is my next step to get fan speed control?

 

Thanks again.

I am changing out my 40 year old rotory controls on my '69 Chris Craft. i have found the colors on the Terminal strips have changed. Existing has  1) Black 2) White 3) Yellow 4) Brown 5) Orange 6) Purple 7) Red 8) White.   New terminal strips have as follows....................1) Green 2) Black 3) White 4) Orange 5) Purple 6) Blue  7) Red  8) White.

So where do the yellow and brown wire go??  This is a straight cool so no blue wire.. Wish I have original wiring diagram.

 

Thanks for hosting this site, it is most bennificial.
