Our carbon monoxide dectector model CO910, bought several years ago (10+) beeps every 30 seconds with an "err" message. All windows where it is are open. No one is feeling ill. Is it just an error on the detector and it is time to get a new one?

Your m
2150 L is likely 25 to 30 years old. The first Riccar vacuums were made in Japan. Your was likely made in Taiwan. Production of most models was brought to St. James, MO 20 years ago. Filters, bags and some parts are still available from your local Riccar dealer, or from ThatVacGuy.com

This could be serious!
Has it been doing this long?
Do you have the manual for it?
What is the beeping code?-- Just 'error'?, or is it telling you that you have HIGH CO Level !?
Carbon Monoxide is a silent killer--- You can't smell it, but it can kill!

The Fire Department has a meter to check it out-- Give them a call and tell them what you have!

I am sure they would rather come for a false alarm, (ONCE!)
than to come and find you unconscious!

You need to resolve this problem immediately!

Hi,
If that is happening the sensor has gone bad inside the unit...you will need to dispose of the unit and buy a new one...

You need to know that very seldom will new carbon brushes alone `FIX`a motor in todays vacuums as they are higher RPM than those of 30 years ago.
On a salvageable motor a good rebuild procedure will generally include repacking bearings, cleaning suction fans and reseating new brushes with an abrasive seating stone at low speed with a motor run in device with variable voltage

That said, I have not done a HENRY in years but it likely will contain a generic AMTEK Lamb type motor as it is sold as more durable vac.
On a traditional vac motor, carbon brushes are removed by releasing a clamp over the brush. The brush holder will have either a flag terminal on it where the wiring will disconnect from the side, or a flat flag terminal which slides into a pocket on the carbon brush housing.
. If you are going to the trouble of replacing the brushes, remove and inspect the old ones for wear and chipping. Also inspect the commutator surface on the motor where the brushes contact. If there are any curved gaps between segments, or if the com is worn like an apple core , you need a motor complete.
If the motor has simply worn to the point where a brush has stuck or worn to nothing, you may be bale to reseat the new brushes, however any evidednce of BLUE sparks or noise is not a good sign . Best of luck. Post back if you need more help

Try turning the knob on top of the machine all the way to the right and try it again
