Understanding the Problem
This guide covers common faults for the DV350AEWXAA-01 dryer (electrical/gas models vary). Use the numbered diagnostic and repair steps below to find the root cause and fix it. Always unplug the dryer (or shut off the gas and unplug) before opening panels. 1) Confirm basic power and user errors - Check the breaker(s) and reset if tripped. For electric dryers, verify the dryer has full 240V across L1-L2 and 120V from each hot to neutral with a multimeter. For gas dryers, confirm a live 120V supply. - Make sure the door fully closes and the door switch isn't engaged by clothing or debris. - Check that control lock/child lock isn't on and that cycle selections are valid. 2) If dryer won't start or won't tumble - First checks: door switch, start switch, thermal fuse, drive belt, motor. Remove front panel to access door switch and start wiring. - Test door switch: Use a multimeter on continuity. With door closed it should show continuity. Replace if open when closed. - Test start switch and any pushbuttons: Verify continuity when activated. - Check motor: If you hear a hum but no drum rotation, motor may be seized or belt slipped. Remove belt and try to spin motor by hand to detect bearing seizure. - Belt/rollers: Inspect the belt for breaks and the idler and rollers for wear. Replace a broken belt or badly worn rollers/guide. - Repair steps: Replace faulty door switch (disconnect wiring, remove mounting screws, install replacement), replace belt by looping around drum and motor pulley and idler, inspect and replace seized motor only if necessary. 3) If dryer runs but does not heat (electric) - Check lint plug/venting first — heavy restriction can prevent heating and trips thermal safety devices. - Test thermal fuse: Locate the thermal fuse on the blower housing. With power off, remove wires and test for continuity. If open, replace thermal fuse. - Test heating element: Inspect element for visible break and test for continuity across the element windings. No continuity = replace heating element assembly. - Check high-limit thermostat and cycling thermostat: Test continuity (cold) — open or out-of-spec = replace. - Check incoming voltage: Electric dryers need ~240V. If only one hot leg present you'll get tumbling but no heat. - Repair steps: Replace thermal fuse, thermostat(s), or heating element. Reassemble, clean vent thoroughly, and test. 4) If dryer runs but shuts off mid-cycle or shows intermittent power - Suspect overheating (vent restriction) or failing thermostats/thermal cutoff, or control/relay problems. - Clean lint filter and vent, then run. If problem persists, test thermal cutoffs and thermostats for intermittent open. - If electronic control shows intermittent faults, inspect harness connections and ground; reseat connectors. Replace control board if failed diagnostics indicate. 5) Loud noise, rumbling, squealing, or scraping - Common culprits: worn drum rollers, bad idler pulley, worn drum glides, motor bearings, foreign objects in blower wheel. - Diagnose: With drum exposed, spin by hand and listen/feel for rough bearings. Remove blower housing to inspect blower wheel for foreign objects and check motor shaft play. - Repair steps: Replace worn rollers, idler pulley, drum glides, or motor as required. Clean or replace blower wheel if damaged. 6) Error code '01' shown with model DV350AEWXAA-01 (interpretation) - Many models use short numeric codes for control or keypad faults. '01' can indicate a control keypad / stuck key, door lock, or a communication fault between modules on some machines. Always check your model’s tech sheet for the exact meaning. - Diagnostic steps: Power-cycle dryer (unplug 1 minute). Run built-in diagnostic mode (if available) to capture stored fault codes. Inspect the console and keypad for stuck buttons or liquid damage. Reseat the console-to-control board connector. If code persists and diagnostics point to control failure, replace the console or main control board. Final safety note: Always disconnect power before testing or repairing. For gas models shut the gas off and, if you remove gas connections to service the unit, have a qualified person reattach and test for leaks. If you are uncomfortable with electrical testing, call a qualified appliance technician.
Common Symptoms
Dryer won't start or tumble, tumbles but no heat, dryer stops mid-cycle, loud rumbling or squealing noises, error code '01' appearing on the console.
Common Causes
- Power supply issue or tripped breaker
- Failed thermal fuse or thermostats
- Broken drive belt, seized motor, or worn idler/rollers
- Clogged lint filter/vent causing overheating
- Faulty control board or stuck keypad generating error code

Helpful Repair Tip
Use a multimeter to check for continuity: thermal fuse and door switch are the quickest, most common single-point failures—if either is open, replace it. Also run the dryer with the vent disconnected (outside) after cleaning the lint to see if heating returns—if it does, it was a venting issue.
Frequently Asked Questions
What does code 01 mean on my DV350AEWXAA dryer?
Numeric codes vary by manufacturer. On many dryers '01' commonly points to a console/communication or keypad input fault, but it can also mean other issues depending on the tech sheet for DV350AEWXAA. Power-cycle the dryer, run the built-in diagnostics, check for stuck buttons or liquid damage on the console, and inspect wiring harness connections. If diagnostics point to the control board or console, replace the failing module.
Can I replace the thermal fuse or heating element myself?
Yes—these are common DIY repairs. Safety steps: unplug the dryer (or shut off gas), remove the appropriate access panel, note or photograph wire locations, disconnect wires, remove the faulty part, and install the replacement. Test continuity with a multimeter before and after replacement. Replace the thermal fuse if it's open; replace the heating element if windings are open or visibly broken. If you’re not comfortable with electrical testing or handling gas connections, hire a qualified technician.
