How to Patch a Swamp Cooler Pump

Like any of your household appliances, the swamp cooler pump installed on your air conditioner needs regular maintenance to be able to give its full utility to you. If it breaks down suddenly in the middle of the heat season, do not lose your cool. You can patch it up by yourself with the help of some tools and materials which you can easily find in any hardware store or home depot.

Materials Needed

  • Asphalt-based sealant
  • Shop vac
  • Socket set
  • Screw drivers (regular and Phillips)
  • New belt
  • Rags
  • Household oil
  • New motor unit
  • Box/open-ended wrench set
  • New water pump
  • Grease gun

Step 1 - How to Know if It Is the Swamp Cooler Pump

A tell tale sign to watch out for if it is the swamp cooler pump that is causing the problem is an air conditioner that is only blowing hot air even if it is on a low cool or high setting. Turn your swamp cooler off and disconnect it from the power source.

Step 2 - Testing the Swamp Cooler Pump

Go to the place where the connection for the water feed hose is located and disconnect it. Put the swamp cooler pump in water and have someone in the house turn it on. This will allow you to see if it has really failed. Dirt and debris may have been pumped into its hoses, causing a clog. If the pump is working, check each of its hoses for clogs. Once you have ensured that they are clear, hook them up with the swamp cooler pump and test it again. If all the clogs were cleared out, water should be flowing freely.

Step 3 - Replacing the Pump

If the swamp cooler pump will not work after trying to patch it up, it may have failed completely and the only way to remedy the situation is to have it replaced. Take it to the store with you to allow you to get the same unit for replacement. Hook it into the water feed hose once you get back home and put the swamp cooler pump in the filter basket. Plug it into a power source and have somebody turn it on. Water should go through freely.

Step 4 - Checking Other Parts

If your swamp cooler is still experiencing problems even if the pump is working well, inspect other essential parts in the appliance, such as the belt. Inspect it for extensive splitting and cracking. If it is really in bad shape, you need to replace it.

Step 5 - Taking Out Squeaks

If your swamp cooler is emitting squeaks while operating, the problem may not be in the pump but in other parts of the air conditioner, such as the motor mount. The mount has to be kept oiled on a regular basis to function properly and to reduce the wear and tear that happens to your swamp cooler unit. Find the lubrication points in the motor mount and put a few drops of lubricant in them. Spin the fan and repeat the oiling process until you notice a slight trickle of oil dropping from the motor mount. Wipe them off with a rag.
