you need to turn off power supply to unit that works ok and leave other unit switched on and code it and test it then switch other unit back on

I have a Master Cool cooler and thermostat and I have never seen this before. Lights 7 and 8 are blinking red. What does this mean?


If you don't have user's manual or if doesn't mention the meaning of blinking lights, look al manufacturer's website, for "Contact Us", see if they have a cusomer's service phone number or a way to leave them a message.

Can not get wine cooler to get cool. Red lights keep,blinking. Need structions on how to set it.


If the light is on and no fan or compressor is running then its your thermostat that is bad. That's the only thing that turns on those parts. As you said the unit is new you should contact your dealer either to replace it.

Keep us updated.

Either the blue LED is faulty or the LED needs replacing or resoldering to make proper electrical connection.
If you cannot fix it yourself and the fan functions normally then don't worry about it.

Hi,

It seems this is either due to faulty fan or fan motor. This could be a reason that the wine cooler is not cooling at optimum rate. As i cannot see the cooler, this is what i could judge from the information you gave to me.

I would still say, it would be worth repair, if this is due to faulty fan or motor ( motor seems to be the main cause ).

The main tough thing would be to get fan motor. You could try to get a replacement motor or a compatible one from the parts store near your home and give a shot. More likely, you would be successful, if the fault is related to motor.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Motor does not go from low speed to high speed If the motor is set to low speed it does not turn on until the high speed range is hit then it tries to go from stop to high speed and throws thw belt

Fan is slow


I dont have a solution, but I have a similar problem with a Bonaire evap rooftop cooler which only started after a tech came to look at the unit when it stopped operating properly last summer. He said it uses less water now, but the issue is that it doesnt cool any where near as effectively with the fan speed so low. I am located in Melb Australia, and wonder if you are in the same area. I am going to call service AGAIN & get the minimum fan speed returned to what it was previously. I wonder if my original unit is too small for the house - but nevertheless, it used to work beautifully and now is a very poor example of evap cooling. The service guy said the base fan speed could be altered from the controller, but we dont know how to get into the setup menu.

This unit is a cooling unit only. I don't know what switch you are looking at but I don't think it's for the evap. cooler(swamp cooler). I am in the Phoenix, Arizona area and it's very common to have a evap. cooler and a seperate heat/cool system as on the hottest days the evap. cooler doesn't cool enough. I hope this helps. Please give me a positive rating. Thank you.
