Hi there! Thank you for reaching out about the clock display on your Frigidaire microwave model FMOS1746BS. We understand how it can be a bit confusing when the clock doesn’t stay on all the time.

By default, this model includes a power save feature that automatically turns the clock display off after a few minutes of inactivity to save energy. That’s why the clock may only show for about 5 minutes before going dark.

If you’d like the clock to stay on continuously, you can disable the power save (sometimes called the energy saver) feature. Instructions for turning off this feature can be found in the user manual for your specific model.

In the meantime, to see the time before disabling power save, simply press the "Clock" button or open the microwave door — either action will bring the clock display back on.

We hope this helps! If you need any further assistance or guidance, please join us via Live Chat at www.frigidaire.com or call our Customer Care Team at 1-800-374-4432. Monday through Friday, 8:30 a.m. to 8:00 p.m. EST, and we will be happy to assist in any way we can. - Patrick
