my evaporative cooler stopped working last summer ,An Evaporative cooler tech told me the thermostat was bad and also needed a new wire from the thermostat to the panel on the roof to the tune of $380 which I did not have , so he did something on the unit panel and left. Now I have to go outside to the breaker box and turn the eval cooler on and off each day by flipping the breaker switch .
Your help is much appreciated .

data cable or T stat wire is being used from the thermostat to the evap cooler panel , is that the standard , can I buy new cable at home depot along w/ a new thermostat ?
It's probably too late for this to be of use but here it is anyway. If your low voltage system is 24V (and it almost certainly is) you'll need Class 3 cable. It will also need to be riser or plenum rated, so CL3R or CL3P need to appear on the cable.
I noticed the thermostat wire on the Master cool unit was deteriorated so I spliced in new thermostat wire ,the old thermostat still did not work
If you do have a low voltage thermostat system then any thermostat with a two stage cooling call should be able to be used with a little work. Photos of connections and model numbers of what you have would be immensely helpful to those trying to assist. Right now there's no information to go on.
I noticed the thermostat wire on the Master cool unit was deteriorated so I spliced in new thermostat wire ,the old thermostat still did not work , I was told that its not as simple as replacing the thermostat because the master and thermostat are specific for the unit due to the circuitry ?
If you like, you could use a line voltage thermostat for the master switch and a toggle switch for the pump. I can appreciate the functionality of that system but it does seem to be a bit much for a swamp cooler. JMHO
I too was surprised at such a configuration. I grew up in West Texas where 90% of people have this type of A/C. It runs constantly to maintain a temp. around 75 inside. If you want timed control, get a time clock. That thermostat will not be at a big box store.
This is the current configuration ( bypassing the thermostat) and thats why I have to turn the unit on and off at the breaker panel , the thermostat/evap cooler is over 15 ears old ,I`m certatin the thermostat is bad Currently CONNECTED on the control panel are as follows : pump-orange, motor orange and pump -black/yellow .
NOT connected : pump/white , Line 1/black , motor/white , Neutral or Line to white pump / black .
Again this is not the original configuration, this was the repair techs work around the thermostat , I don`t use 2 pumps so disregard the 2nd pump connection. My goal is to put it back to the original configuration which is why I need your help , there are no pics of original configuration.
