Troubleshooting Fantech DB10 Fan
Having trouble with your Fantech DB10 fan? Let’s break down the common culprits so you can get that air moving again. We’re focusing on power glitches and giving the sensor and motor a little TLC.
Potential Power Issues
Got a DB10 that’s as quiet as a mouse? The fan’s power comes from a pressure switch that should always have 115 volts ready to go. If the fan ain’t spinning, we’re looking at a few power hiccups.
First off, grab a multi-meter and check if your pressure switch is getting that sweet 115 volts:
- Set your multi-meter to AC voltage.
- Pop those probes on the pressure switch input terminals.
- Watch for the magic number—115 volts.
| Component | Voltage (V) |
|---|---|
| Pressure Switch | 115 |
| Motor | 115 |
| Control Board Input | 115 |
No juice at the switch? It might be a problem upstream with the power source. If the switch has power but ain’t sharing it with the motor, it could be a bad switch.
Make sure the switch is doing its thing—sometimes energy-efficient dryers don’t wake it up because they’re light on electricity (Dryer Booster Fan).
Sensor and Motor Exam
Checking the sensor and motor is next. The sensor gives the fan a nudge to start, while the motor gets those blades moving. If either’s slacking, we need to step in.
- Give the sensor an inspection:
- Make sure it’s where it should be and not jammed up.
- Check it’s getting love from the dryer.
If it still refuses to wake up:
- Unhook the motor from the control board.
- Get out the multi-meter and test those motor windings for continuity.
- Attach those probes to the motor terminals. Continuity means the windings are snug and intact.
Still puzzled? Give direct power to the motor and see if it spring to life:
- Carefully plug 115 volts AC right into the motor terminals.
- Does it hum to life? The sensor or control board may need a timeout.

| Issue | Indication |
|---|---|
| Sensor not receiving signal | Fan stays off |
| Motor windings are toast | Multi-meter shows no continuity |
| Sensor or board giving you guff | Motor runs when bypassing it |
Getting these pieces sorted can solve your Fantech DB10 woes. If you’re still stuck, the control board might want a swap-out. More nitty-gritty on that in Addressing Control Board Concerns.

Diagnosis with a Multi-Meter
To get to the bottom of dryer booster fan issues, a multi-meter is your go-to gadget. This guide will walk you through the steps of testing electrical connections and pinpointing faulty parts to figure out why your dryer booster fan decided to take a break.
Testing Electrical Connections
Before you start poking around wires, make sure the dryer is unplugged so you don’t end up with a shocking experience. With the power cut off, you can use a multi-meter to check the different wires and parts.
- Check Power to the Pressure Switch:
- Set your multi-meter to AC volts.
- Measure the voltage at the pressure switch. You’re looking for around 115 volts. No juice? Then you’ve got a power problem leading to the switch.
- Test the Pressure Switch Output:
- If the input voltage checks out, flip the multi-meter to continuity mode.
- Turn on the pressure switch and look for continuity. The switch clicks but doesn’t pass power to the fan? That switch might be on the fritz.
- Inspect Wiring Connections:
- Go back to measuring AC voltage with your multi-meter.
- Check between the switch and the motor. Make sure the motor gets its power when the pressure switch is on the job.
Identifying Faulty Components
Identifying faulty components is about checking each bit of the booster fan setup:
- Pressure Switch Examination:
- Measure the voltage at the pressure switch terminals.
- If the switch clicks but doesn’t pass power to the motor, it’s likely busted. Need more help? Check out our article on dryer moisture sensor issues.
- Motor Check:
- Swap the multi-meter to ohms for measuring resistance and test the motor windings.
- Finds an open circuit (infinity)? That’s a burned-out motor. If it shows continuity but refuses to spin, it might be jammed or have other problems.
- Control Board Analysis:
- If power problems stick around, the control board might be to blame.
- Check continuity and power flow through the board parts. If it’s gone haywire, the whole control board assembly might need a swap (JustAnswer).
| Component | Expected Voltage/Resistance |
|---|---|
| Pressure Switch | 115 volts (AC) |
| Motor Windings | Low Resistance (Ohms) |
| Control Board | Steady Voltage Flow |
By using a multi-meter right, you can figure out why your dryer booster fan’s not running. Nailing down proper electrical connections and zeroing in on faulty components is what will get your system back up.

Pressure Switch and Diaphragm Check
Pressure Switch Functionality
The pressure switch in a dryer booster fan is like the manager at a party, ensuring everything runs without a hitch. It must always be at 115 volts. When it’s on the job, it sends power to the fan. Problems pop up if there’s no power at all, if the switch is just lazy and won’t send power to the motor, or if the motor’s taken a permanent vacation (JustAnswer).
Want to test this switch yourself? Here’s how:
- Verify Power Supply: Make sure the switch has a steady 115 volts. A multi-meter helps out here, checking the electrical connections.
- Activate the Switch: Give a gentle puff into the tube attached to the pressure switch, holding for at least five seconds. When the switch is feeling it, it clicks and starts the fan. Expect two five-minute rounds of fun with a quick 20 to 30-second pause between (JustAnswer).
Troubleshooting Clicking Switch
If you hear clicking but the fan won’t join the party, the issue might be a grumpy switch. Here’s how you might troubleshoot:
- Inspect the Switch: Sometimes, it clicks but still won’t chat with the motor. It may need replacing.
- Check Power Relay: Peek at the power-in route through the control board. If power isn’t getting through, the control board might be the party pooper and need replacing (JustAnswer).
| Issue | Possible Cause | Solution |
|---|---|---|
| No Power to Switch | Electrical Fault | Check circuit breaker and wiring |
| Switch Clicks, No Power to Motor | Faulty Switch | Replace the switch |
| Continual Power Issues | Control Board Malfunction | Replace the control board assembly |
