When to replace the blower motor power transistor?
When to replace the blower motor power transistor?
If the resistance IS NOT within specification, we can conclude your Honda Civic’s blower motor power transistor is bad and needs to replaced. Now, if the resistance is within specification, then we need to continue on to the next test (which is testing the power transistor diode).
What are the symptoms of a bad blower motor relay?
3. Melted relay. Another more serious symptom of a problem with the blower motor relay is a burned or melted relay. Relays are exposed to high current loads and can sometimes get hot when they develop problems.
How many amps does a 10 hp blower draw?
The 16 amps is a full 7.5 amps under the FLA rating of the motor. The FLA is the full load amps or the amperage the motor will draw if it is doing its rated horsepower worth of work. For this motor, if it is doing a full 10 HP work load, it would draw 23.5 amps, it is only drawing 16 amps. This shows there is more HP available.
What should the CFM of a blower be?
The goal is to increase the cfm from 3000 cfm to 4000 cfm. Changing a pulley size or making an adjustment on the motor pulley if it is adjustable will accomplish this. The most economical and practical pulley to replace is the motor pulley.
What are the symptoms of a worn out blower motor?
One of the symptoms of a worn out blower motor is that it can intermittently produce a loud screeching noise when running. How to test a blower motor? If the blower motor doesn’t work at all, the blower motor itself must be tested first. Typically it’s done by measuring the voltage at the blower motor connector when it’s turned on.
How to test the blower control module 3.8L?
Where To Buy The Blower Control Module And Save. TEST 1: Verifying The Blower Control Module Is Getting Battery Power And Ground. TEST 2: Bypassing the Blower Control Module. TEST 3: Verifying The Blower Speed Voltage Signal. More 3.8L GM Tutorials.
Where is the number 1 on a blower motor?
Disconnect the blower motor from its two-wire electrical harness connector. Connect one end of the fused jumper wire to the blower motor male spade terminal labeled with the number 1 (in the illustration). This is the terminal that connects to the BRN/YEL wire of the connector.
How many ohms does a blower motor resistor need?
According to the service manual, it must be around 4-5 ohms. In our case the ohmmeter shows open circuit, which means the resistor has failed. Sometimes, a blower motor resistor might fail due to problems with the blower motor itself.
