Question about Mastercool 67471 Evaporative Cooler Air Conditioner

3 Answers

I have a Mastercool Evaporative cooler and had the filter replaced two days ago. It still has a very bad odor (like a swamp!) The water was drained and replaced, as well. What I can put in the cooler, that is safe to breathe, to get rid of this odor?

Several of us add scented fabric softener at start-up each year, and later add a bar of ivory soap. I also have an in-line 'scale eliminator' and an anode inside , as well as a purge pump, which changes out all the water every 8-12 hours. These things combine to keep fresh water in the cooler, and suspend minerals. With clean pads, that should keep foul smells away.

I suggest putting a piece of Ivory bath soap in the water trough.(about 1/2 of the large bar.
it will float and will not clog the system. I have been doing this for years and it eliminates a considerable amount of oders and helps keep the scale build up to a minimum.

Evaporative cooler pumps in dust


You should not have dust. Your water pump is probably shot. The hoghair might need to be replaced or the whloe unit might need a good hosing down. As far as a draft all the time? That is what you want in an evaporative cooler ain't it?

Mastercool swamp cooler fan doesnt come on.


Are the relays perment on the board or are they seperate from the main board? If they are mounted to the board, you will need to replace the board. Sounds like you are getting a call to the relay but none leaving so this would indicate that you have a bad relay switch.
