Please response if this answer is acceptable and solw your problem thanks

There are a few possible reasons why your Lasko oscillator heater might be turning off after 10-15 minutes of operation.

Overheating: If the heater is overheating, it will automatically shut off to prevent damage. This can happen if the heater is blocked or if it is in a dusty or dirty environment.

Faulty thermostat: The thermostat may be malfunctioning and causing the heater to shut off too early.

Dirty or clogged air filter: A dirty or clogged air filter can restrict airflow and cause the heater to overheat.

Problem with the fan: If the fan is not working properly, it may not be able to circulate enough air through the heater, which can lead to overheating.

Problem with the power cord: A damaged or faulty power cord can cause the heater to shut off unexpectedly.

To troubleshoot the problem, you can try the following:

Check the heater for blockages. Make sure that there is nothing blocking the intake or exhaust vents of the heater.

Clean the air filter. Remove and clean the air filter according to the manufacturer's instructions.

Check the fan. Make sure that the fan is turning freely and that there is no debris blocking the blades.

Inspect the power cord. Make sure that the power cord is not damaged or frayed. If the power cord is damaged, replace it immediately.

If you have checked all of these things and the heater is still shutting off, then it is possible that there is a problem with the internal circuitry of the heater. In this case, you will need to take the heater to a qualified repair technician.

Here are some additional tips for keeping your Lasko oscillator heater in good working order:

Clean the heater regularly. Use a damp cloth to wipe down the exterior of the heater and to clean the air filter.

Store the heater in a clean, dry place when it is not in use.

Have the heater inspected by a qualified technician on an annual basis.

I hope this helps!
