Refrigerator Mods - Hi-Lo camper travel trailer forum

I have made the fan upgrades on my 2207T ... with a twist of course. The vent on the 2207T is smaller than on previous installation ... especially older hi-Lo's so I didn't feel adding the plenum was necessary. I replaced the stock five blade 120mm box fan with two ultra quiet seven blade single speed 140mm fans using homemade brackets. The fans turn on with the standard "Refrig Fan" switch and stay on until I turn them off. (Correction, they are turned on and off by the thermal sensor on the refrigerator fins ... the master switch in the Hi-Lo only activates this function ... but the mater switch does turn the interior refrigerator fan/light on and off)

The interior fans are really intended for cooling a PC hard drives and are available for about $6.00. I made mounting clips to attach the fans to the cooling fins out of electrical grounding clips intended for MC cable from Home Depot and some old screws which I ground the sides off to make them a "T" shape ... careful use a pliers to hold them as they get "_ucking" hot! The LED unit is rated at 100,000 hours so I am not worried that it is on while the fans are on ... oh! these fans switch on with the "Refrig Fan" switch too!

Update: for the "blue fans" just Google "HDD fans" and you will have more sources than you can shake a stick at!

Where did you find the blueish housing interior refrigerator fans?

John,

Very clever using J-box grounding clips! I'll remember that for other applications. Nice work!

Very nice work, John. I'll be interested in how they seem to work when in use.

We'll be off to the mountains of New Mexico next Sunday, so I'll be able to report on my version.

Newer version of the same thing here.

PS - I have personally used MWave many times and can tell you shipping is very quick, prices are very resonable and I have only ever had something come to me dead ance and they replaced it VERY fast...
