Oasis water cooler model # B1RRPK-D102. The water in the reservoir freezes! We have cleaned the system, but no improvement. Any sugggestions? Thanks, Lucy

It's important to be cautious when rewiring a relay, as incorrect wiring can cause damage to the water cooler or even create a safety hazard. If you're not familiar with electrical wiring, it's best to consult a professional to do the job.
Assuming you have the replacement relay and know which wires connect to it, here's a general guide to rewiring a relay:

1. Turn off the power to the water cooler. This is essential for your safety.
2. Locate the relay and remove the wires from the old relay. Note the color and position of each wire so you can connect them to the new relay correctly.
3. Connect the wires to the new relay in the same positions as they were in the old relay. The most common connections are:
4. The black or brown wire should connect to the "L" terminal of the relay.
5. The white or grey wire should connect to the "N" terminal of the relay.
6. The red or blue wire should connect to the "C" or "NC" terminal, depending on the relay type.
7. Double-check that all connections are tight and secure. Loose connections can cause problems, such as arcing or overheating.
8. Turn the power back on and test the water cooler to ensure it's functioning correctly.
Again, if you're unsure about rewiring a relay, it's best to seek professional help.

If your car has an automatic transmission, The transmission cooler lines attach to the radiator,The transmission cooler is located inside the radiator, It might be leaking into the coolant system. Check your transmission fluid level.

If it is transmission fluid it is likely the heat exchanger (or cooler) has sprung a leak. The cooler is often integrated into the main radiator bottom tank. If fluid is entering the cooling system it is possible coolant could be entering the transmission.

Tranny fluid will appear clean and floating on the surface of the coolant and is likely to be pink or red while if it is engine oil it will be an altogether dirtier colour and more viscous. Try capturing a sample with some clean white tissue when the engine is cold.

Engine oil in the coolant could be a sign of a failing cylinder head gasket.
A failing head gasket is likely to produce unusual cooling system symptoms including ejecting coolant from the reservoir while a leaky tranny oil cooler is unlikely to have much effect on cooling system behaviour except for the obvious...

This sounds like the thermostat has failed.
A new thermostat needs to be fitted

Sounds like you have a blockage check/ clean remove dispenser to do

Pull the water jug and open the top of the unit. Look for frozen water. May need repaired or adjusted to keep water from freezing.

I just put about six cups of white vinegar (not diluted) into the reservoir and let it sit for about an hour. Then I emptied that out and flushed a few pitchers of very hot water through. It seems to have worked quite well.

if the cooler is a hot and cold, even if its a cook and cold, the cooler always needs to be cleaned and maintained, not only on the inside but on the outside, as the cooler is used calcium builds up over time. that is why your taps are leaking, there is a build up in the taps, therefor the taps are not sealing properly and letting some water thru. i say take the taps out and clean them with vinegar.
the second thing u can do is the taps do come apart into smaller peices once u disconnect them from the cooler. take the taps apart and find the spring located within it, stretch the spring and than reconnect the peices together than reconnect to the water cooler.
