Fisher & Paykel SmartLoad Dryer Code 9: Exhaust Temperature Too Low

What Code 9 means

Code 9 on Fisher & Paykel SmartLoad and AeroSmart dryers, including the DEGX1, DGGX1, DE27CW1 and DG27CW1, means the exhaust sensor reads an under temperature, below 14 F (-10 C). A reading that low is not realistic for dryer exhaust, and it typically points to an open-circuit thermistor. The display shows the code and the dryer stops or will not heat.

Common causes of Code 9

An exhaust sensor thermistor with an open circuit
A loose or broken sensor connector
Damaged wiring between the sensor and control
A sensor module that misreads the signal

✓ One safe check you can try

1. Switch the dryer off at its breaker for a minute and restart it. 2. Run a short cycle with a small load. 3. If the dryer is in a very cold garage, let it warm to room temperature first. 4. If Code 9 appears again, do not open the cabinet. Leave the dryer off and call us to test the sensor.

! Why to stop there

The reading is almost certainly a sensing problem, not real cold air, and a meter is needed to prove it.
A thermistor is a small, low-cost part, but reaching it means working inside the cabinet.
We test first so you do not pay for parts that are fine.
Written pricing comes first, and we back the repair with a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Code 9Code 9 questions

Why would a dryer think the air is below 14 F?

The sensor is a thermistor whose resistance changes with heat. If its circuit breaks open, the control reads an extreme cold value, and Code 9 appears.

Is the dryer actually cold inside?

Not usually. The reading is false, caused by the open sensor circuit, so the dryer shuts down for safety even though the air is fine.

Could a cold laundry room cause it?

Only an extremely cold room would, and it would be unusual. If warming the room does not change anything, the sensor or its wiring is the likely cause.
