Before digging into the details, let us give you guys a quick overview of the blower sleeper fuse, especially if you already don’t know about it.

Blower Sleeper Fuse: An Overview

The HVAC blower sleeper is a motor that pushes the cold or warm air according to the needs of air conditioners, cars and trucks. So, you can keep the ACs and other vehicles warm or cold according to the seasonal requirements with the help of this motor.

 Blower Sleeper Fuse

A fuse or relay powers this blower motor or sleeper. If your air conditioner is not pushing the air through the vents, it means that the sleeper motor has blown away. You have to fix or replace the engine for better air blowing. Remember that the type and location of the blower motor or sleeper vary according to vehicles and air conditioners.

That’s why it’s better to know the types and locations of sleeper fuses of each kind of vehicle before resetting or replacing them yourself.

Well, the blower fuse is in the fuse panel of the AC under the dashboard. However, this fuse’s power and capacity depend on the air conditioner’s type and intensity. Moreover, the blower fuse capacity also depends on the required blower speed. If the fuse has blown away, your AC will stop working or push the air through the vents.

The AC unit will remain working even after the fuse has blown away. However, the current will not pass through the fuse. Ideally, checking the blown-out fuse would be super easy if you have a voltmeter and know how to use it safely.

Things To Consider Before fixing Or Resetting the Sleeper Fuse

It’s not compulsory or essential that your AC stop working because of a blown a fuse. That’s why it’s better to determine the main reason for the AC tripping or stopping working before replacing the fuse.

Your AC can also stop working because of a circuit break or improper power supply. So, fix these issues before considering the replacement of the fuse. On the other hand, improper AC maintenance may also cause a stop working.

If the outdoor AC unit is not working, check the circuit breaker or tripping panels. You can quickly turn on the outdoor unit of your AC only by setting the circuit breaker panel. Also, check the thermostat panel to see if the AC is still malfunctioning or turning on.

Frequently Asked Questions

How to find out if the HVAC fuse is blown?

Place the meter’s leads on the load wire lugs to check for voltage on the load side of the fuses if there is the voltage on the line side. The voltage reading on this side indicates that the current passes through the fuse. Zero voltage indicates a blown a fuse if you detect it on the load.

What are the reasons behind a blown HVAC fuse?

Fuse blowing can be caused by dirt and dust, especially if your boiler hasn’t been cleaned. This dust can go from your filter to the blower motor, which may overheat the motor and eventually cause it to burn out and blow a fuse.

Can I repair the HVAC fuse?

Luckily! Yes. Blown fuses are a rather simple DIY home repair. You can get back in operation with a basic understanding of your fuse box and a short trip to the hardware store. Always follow the correct safety precautions when handling electricity.

Are blown and HVAC faulty fuses the same?

No! A blown fuse indicates a short circuit. When a gadget malfunction, an electrical component can draw more current than it was intended to handle.

Hopefully, the above guidelines and steps mentioned are enough to reset the HVAC blower sleeper fuse yourself.
