How to replace the over heat switch on a lasko 5622 heater and how to tell if this why heater shuts down after 5 minutes . I have cleaned heater and it still shuts down

they do wear out and need replaced

Either the Overheat switch, or perhaps the Tilt switch is shutting down the unit.

Make certain there is nothing in front of the unit.

Make certain the unit is flat on the floor.

don't send anything to Fixya. Please contact your dealer, or the site where you bought this.

fatly over heat switch or tilt switch some r very picky

Hi , problem can bee in termoregulation , or temperature switch inside of him (overheating).

Sounds like the bearings goig bad in the motor, just replace the motor.(Internet or website)

mine does the same thing every year. I just clean out the dust from the vents on the back of the heater so the heater can breath otherwise it could get too hot and the safety fetcher kick in and makes the heater stop working.

Blow the dirt off the filter in the back... then shut it down for 5 min. it should then work..

i have the same problem ... i almost throw this heater out ,,
the fix .. open the unit theres 6 screw at the back.. remove it if you have problem removing the triangle screw use the small square head screw ...size 0 and then you also need to open the black plastic ..
i believe it has 8 screws .. then vaccuum all the dust .. chances are the front and the back of the heating element is covered with dust ..
after that put all back together and i guaranteed it should work like brand new ,,,, dont worry its not that hard ... the only hard thing for me was removing the 2 triangle screws at the back .. Goodluck
