Understanding the Problem
Brief explanation: Your GE dryer model GTD45EASJ0WS that "won't turn on" can mean different things: no lights or display, drum won't start, or no noise at all when you press Start. The most common causes are loss of electrical power, a failed door switch, a blown thermal fuse, a failed start switch or motor overload, or a faulty control board or user interface. Follow these numbered diagnostic and repair steps to find and fix the fault. Step-by-step diagnostic & repair instructions: 1) Confirm basic power and breakers - Check the home's circuit breaker or fuses for the dryer. Reset any tripped breaker. Electric dryers usually require a double-pole 240V breaker; both poles must be on. - Test the outlet: unplug the dryer and use a multimeter set to AC voltage to measure across the hot terminals. You should read ~240VAC across the two hot legs and ~120VAC from each hot leg to neutral (if neutral is present). If uncertain, try another 240V appliance or call an electrician. If there's no power to the outlet, stop here—repair the household circuit. 2) Check the dryer power cord & terminal block - Unplug the dryer and pull it away from the wall. Remove the access panel behind the dryer to inspect the cord connections at the terminal block. - Look for loose wires, burnt/cracked insulation, or melted terminals. Tighten loose screws and replace a damaged power cord/terminal block. - Replacement tip: use a 4-prong or 3-prong cord appropriate for your installation. Make sure connections are tight and the grounding strap is correct. 3) Verify basic control power (console lights/LEDs) - Plug the dryer back in. If the control/display has no lights at all, power to the control is not present (board or supply issue). If some lights are present but the dryer doesn't start, the issue is likely a start circuit, door switch, or motor. 4) Test the door switch - The dryer will not start if the door switch is open. Unplug the dryer, access the door switch (usually at the door opening or behind the front panel), and test for continuity with the switch actuated (door closed). If there's no continuity when closed, replace the door switch. - Replacement: remove the front panel or access the switch from the door opening, disconnect the wiring harness, swap the switch, reconnect and test. 5) Check the thermal fuse (on the blower housing) - The thermal fuse is a one-time protective device that will open if the dryer overheats; when blown it prevents the dryer from running. Unplug the dryer, remove the front or rear panel to locate the thermal fuse on the blower housing (small rectangular component). Test for continuity with a multimeter. If open (infinite resistance), replace the thermal fuse. - Replacement: remove screws that hold the fuse in place, take off the wiring, fit new fuse and reassemble. Note: Replace only with the exact OEM thermal fuse rated for your model. 6) Test the start button/switch and timer/selector switch - For push-to-start models, test the start switch for continuity when pressed. For mechanical timers, test the switch positions that feed the motor. If the switch is faulty, replace it. - Access: console or selector assembly. Unplug dryer, remove console screws, test switch terminals with multimeter. 7) Inspect the motor and motor overload / centrifugal switch - If you hear a humming or click when pressing Start but the drum doesn't turn, the motor may be jammed, or the motor start winding or centrifugal switch has failed. Unplug dryer, spin the drum by hand—if it's seized, check the belt and idler. If the drum turns freely but motor doesn't run, bench-test the motor or replace the motor assembly. - If the motor runs intermittently, the motor thermal protector may be opening—test motor windings for continuity and insulation. 8) Check the control board / user interface - If you've verified power, door switch, thermal fuse, start switch, and motor but the dryer still won't turn on, the main control board or console user interface may be defective. Look for burnt components, scorch marks, or swollen capacitors. Test outputs from the board (only if you are comfortable and qualified) — verify the board provides power to the motor or contactor when Start is pressed. - Replacement: remove the control console and replace the control board or user interface assembly with the OEM part for your exact model. 9) Final testing and reassembly - After replacing a failed part, reassemble panels, restore power and run a short cycle to confirm operation. Check for proper drum rotation and heating behavior (for electric dryers check heating separately). Safety note: - Always unplug the dryer or switch OFF the correct breakers before opening the cabinet. Use insulated tools and a multimeter rated for household voltages. If you are not comfortable working around mains electricity, call a qualified appliance technician or electrician.
Common Symptoms
No power to console, no drum movement when Start pressed, no lights on control, dryer sometimes hums but won't start.
Common Causes
- No electrical power to the dryer (tripped breaker, faulty outlet, damaged power cord)
- Failed door switch or blown thermal fuse (dryer will not start for safety)
- Faulty start switch, motor, or main control board/user interface

Helpful Repair Tip
If the dryer has no lights or display at all, start with checking the circuit breaker and then the dryer terminal block/power cord—these are the most common non-repair-shop causes. If the display lights but the drum won't start, check the door switch and thermal fuse next.
Frequently Asked Questions
What if the dryer has power but won't start when I press Start?
If the console lights up but the dryer won't start, first check the door switch and the thermal fuse for continuity. Then test the start switch and listen for any click from the motor when you press Start. If you hear a click but the motor doesn't run, suspect the motor, motor overload, or the centrifugal switch. If nothing clicks, the start switch or control board could be at fault.
Can I test and replace these parts myself?
Yes — if you are comfortable using a multimeter and working safely around household electricity. Always unplug the dryer and follow the safety steps. Testing continuity on the door switch, thermal fuse, and start switch is straightforward. Replacing the thermal fuse, door switch or power cord is usually a medium-difficulty DIY job. Replacing the motor or control board is more advanced; if you are unsure, call a qualified appliance technician.
