Why would Big Tex Air in Pflugerville charge $600/hour and sell me a used fan that was supposed to be new? It is also common practice for the general manager (Willie Ridgeway) to answer the office phone and pretend to be someone else? Is he too ashamed of his company? Is it also common practice to detect leaks in the attic without looking at the equipment?

The motor uses the fan air flow to cool it. Idealy motors should run cool but for cheapness the manufacturers cut corners.

Put it on. The big pulley is also a big fan. So it should blow air on the pumping unit. This is it. If it spins in the wrong direction change the polarity. If you look close you should see somvere a rotation direction indicator .

Let's do the overheat first.
Your van should have 2 electric fans or maybe 3, under the hood and directly mounted to the radiator.
There are usually two behind the radiator, and one in front, or visa-versa.
One of these fans is supposed to kick on immediately when you start your AC. It is probably not doing so.
The 2 things that usually cause it to fail are a bad relay or a bad fan motor.
While you are checking all this, be sure to check the other fan and fan switch (screwed in to the bock) and make sure it is working right.
The second part is much harder.
Here in Florida, where it is nearly always AC weather, I've noticed that when the van gets hot, it can take 1/2 hour to cool it. ( 100 degrees).
I have found some cars just never really cool down, so I make a real effort to always park in a shady spot and/or under a tree, and that makes a big difference in the passenger comfort.
Some car pats stores sell a dash-mounted electric fan, the kind people used 70 years ago.
Be blessed.

Never haven used one, I'd see if the directions that came with it tell you anything. If not, I'd go with the fairly common practice of a 12-hour charge that many manufacturers recommend for electronics.

Do you have the Tstat set to low? are you trying to cool to big of a room? Is it relly blowing out cold air? You might want to shut it down for an hour or so and let it deice. Or it low on charge? have you serviced the filter latley ? My bet is the filter is dirty. and you cooling to big a room and its iced up so shut it down and see if after anout one or two hours you trun it back ona dn get more air flow.. close off unused rooms and place floor fans a round

if you still want one i'm selling my nearly new unit.

modified with larger hard drive and screen covored vent holes for air flow
even added fans inside to move the air.

been in use a whopping 2 months, unfortunately i might not have a phone line to use it any longer.

Without knowing the background of your experience with the unit, it is a bit hard to determine if it is a hardware / software problem. I suppose the first thing is to decide is, are there any habits that you have developed when using the unit that may contribute to the problem of rapid battery deterioration.

When you are using the unit, do you leave turned on for long periods in between reading sessions?
When you finish using the unit, do you switch off by gently sliding the off switch or do you completely turn it off by sliding the switch to the right and holding it for 2-3 seconds?
When you charge the battery, are you confident that the battery is fully charged before disconnecting? (The handbook will help to describe when this state is achieved.)

I guess you are using the unit properly in which case it is almost certain that it is a hardware / software problem and needs to be returned. If you go this route you probably either need a new battery or if the hardware is faulty, a replacement unit.

Despite the problems you are experiencing, I have to say that the normal cycle between charges of my PRS-600 is not as long as I expected or hoped. In my case, this is about 5-8 days of steady use at about 1/2 to 1 hour per day.

Hi there,

On every electronic that use a cell battery, that need to be charged and discharged after every use.

The very common easy steps on how to make your battery life last longer is just practice the complete the charged/discharged cycle of the battery.

You nee to at least once a wee to completely discharged the device battery, and charge it on the prescribed charging hours. Do not exceed on the number of hours the battery has to be charged.

Hope this initial information/idea helps. Let me hear from you again for any other instructions.

Thanks

It is unlikely that the water pump is causing the trouble you describe. The large hex behind the fan is what you would turn to remove the fan clutch from the water pump shaft. This fan clutch is supposed to detect heated air coming through the AC condenser and radiator and engage the fan more positively with the water pump shaft when more air needs to me moved to cool the radiator and AC condenser. The fan clutch could be bad or the AC system may not be properly charged--either of these conditions could cause the problem you describe.

Chech the fans rotation , the fan is suppose to blow air out the top, also if you changed the fan out ,check for the blade on right, its suppose to scoop the air from the inside and blows it out the top,, also replace the capicator...sounds to me like the motors getting too hot and tripping on internal ly high temp. Hey, slow down "Big Money"! The problem is around the fan location! Thank-you-very-much!
