Wagner Paint Sprayer Motor Not Turning On [FIXED]

If you are having issues with your Wagner paint sprayer motor not turning on, it could be due to several reasons. The motor is one of the most crucial and most expensive parts of the sprayer. It is also one of those parts that would be better to replace rather than fix. Overall, you won’t want to have any problems with the motor just yet. 

However, if the motor fails to turn on, you won’t have to save for a replacement immediately. There are several steps you can take to troubleshoot and fix the issue. In this guide, we will go through the most common causes of this problem and provide instructions on how to fix them.

How to Fix Wagner Paint Sprayer Motor Not Turning On: DIY Fixes

1. Check the Power Supply

The first thing you should do is make sure that the power supply to the paint sprayer is functioning properly. This can be as simple as checking to see if the outlet is working, or if the extension cord is properly plugged in.

If the outlet is not working, you will need to find another outlet to use or try a different power source. If the extension cord is not properly plugged in, make sure that it is plugged in all the way.

2. Check the Fuse

If the power supply is working properly, the next step is to check the fuse. The fuse is responsible for protecting the sprayer from power surges and other electrical issues.

If the fuse has blown, the sprayer will not turn on. To check the fuse, you will need to locate the fuse box and find the fuse that corresponds to the paint sprayer. If the fuse looks burnt or damaged, you will need to replace it.

3. Check the On/Off Switch

If there are no issues with the power supply and the fuse, you should check the on/off switch. The on/off switch is located on the front of the sprayer. Obviously, the function of the switch is to turn the sprayer on and off.

If the switch is not functioning properly, you will notice that the motor will not turn on as it should. To check the switch, simply turn it on and off a few times to see if it is working properly. If the switch is not functioning properly, you may need to replace it.

4. Check the Hoses and Filters

Another area that could be the problem and should be checked is the hoses and filters. The hoses and filters can sometimes become clogged, which can prevent the sprayer from functioning properly.

To check the hoses and filters, you will need to remove them from the sprayer and inspect them for any clogs or damage. If the hoses or filters are clogged or damaged, they will have to be replaced.

5. Check the Electrical Cord for Damage

This issue with the power supply could also extend to the electrical cord. If you’ve not been able to get the sprayer to turn on after applying all the fixes above, then you should inspect the electrical cord for damage.

There could be rips, cuts, or heat damage to the insulation or inner wires. If you notice any of these issues, then you will need to get a replacement. Also, check if the wires are exposed or if there are any missing ground prongs. 

6. Check for Thermal Overload

Overheating is not a common issue with the Wagner paint sprayer, but if you’re still having issues with the motor, then you might want to consider this fix. Check that the vent holes to the enclosure of the motor are not covered. If there is no proper airflow, the motor might get overheated.

Chances are that your Wagner sprayer comes with a thermal overload switch that shuts down to prevent it from damage due to overheating. To confirm this, you can hold your hand near the motor and feel its temperature. If it does feel hot.

Wait for about an hour till it cools down, before trying to restart it. In some cases, the overheating issue could be due to running the sprayer at high pressure with a very small tip. Avoid using this method for long periods of time to prolong the motor lifespan.

How To Maintain The Wagner Paint Sprayer

With proper maintenance, you can actually prevent issues like the motor not turning on and prolong the lifespan of the sprayer. You can use the maintenance tips we have provided below to get started.

Clean the sprayer thoroughly after each use. This is important to prevent dried paint from clogging the nozzle and other parts of the sprayer. Use the manufacturer’s recommended cleaning solution and follow the instructions provided in the user manual. You should also follow the manufacturer’s guidelines on the frequency of cleaning. This is usually based on how frequently, you use the sprayer

Inspect the nozzle and replace it if it is damaged or clogged. A clogged or damaged nozzle can affect the quality of the paint finish and cause the sprayer to work less efficiently. Always check the nozzle before and after every use to ensure that it is in perfect working condition.

Check the hose for any kinks or damage and replace it if necessary. A damaged hose can cause a loss of pressure, resulting in poor paint application. You should easily notice if there are any problems with the hose and fix them immediately. 

Lubricate the moving parts of the sprayer according to the manufacturer’s recommendations. This will help to keep the sprayer functioning smoothly and reduce wear and tear on the parts. This is one of the most important tips when it comes to ensuring that the sprayer lasts longer.

Store the sprayer properly when not in use. Make sure to store it in a dry place to prevent rusting and other damage. Check the user guide on how to properly store the sprayer. 

By following these maintenance tips, you can help ensure that your Wagner paint sprayer continues to function effectively and efficiently.
