Yes, the thermal fuse could cause all of the lights to stop working, depending on how it is wired on model 619004EX. Since you’ve already replaced the bulbs and none of the lights work, I would test the fuse before replacing anything else.
Unplug the unit first. Remove one wire from the thermal fuse and check it with a multimeter on continuity/ohms. A good fuse should read close to 0 Ω / continuity. If it reads OL/open, the fuse has failed and should be replaced.
If the fuse tests good, the next thing I’d check is the light switch. With the switch ON, it should have continuity through it. After that, you would need to check whether 120 VAC is actually reaching the light circuit.
One important point: if the thermal fuse is blown, also check for an airflow/overheating problem before replacing it. Thermal fuses normally open because the area became hotter than it should.
Thanks for your help, it was the fuse, changed and all is good.
