Question about Lasko Ceramic Heater

Lasko heater beeps too LOUD

I have a Lasko electric space heater. It works great, except whenever you press a button on the unit or the remote, it makes a super loud beep. It is painfully loud and will wake up anyone in the house.
I'd like to disable the speaker. Has anyone had any luck doing this?

It is a Lasko model 6000.

    Thanks for the reply! Just 2 years late. :)
    I actually did the same thing as you last year. I took apart the heater and unsoldiered the speaker from the circuit board. We have 2 different heaters and I did the same to both that day. They've worked fine ever since with no beeping at all.
    Each of the 2 heaters had a couple special screws where hard to get. I think on one I filed down the center of a flat head screw driver to get it to work.

I was cleaning out my Lasko ceramic heater 6000, looking for instructions on how to do so, and came across your comment. After I opened it up and cleaned everything out (really easy, no instructions needed, it is all obvious) I started thinking about how much I hate that beep as well. So I decided as long as I had it opened to try to disable it.
Well, I could tell from plugging and unplugging that it was (unfortunately) mounted on the under side of the green circuit board. You will have to unscrew the circuit board completely (all wires still attached) and (carefully!) move it so you can flip it upside down to get to the other side. Note: there were 7 screws to remove and 1 was under the motor and really hard to get to. The motor looked WAY too complicated to remove so I got the screw started just a little with a precision screw driver and turned it the rest of the way with needle nose pliers.
Once the circuit board is off, the beeper is a little black circular thing (about 1/2 inch in diameter) with a little hole in the middle. It has a serial number on it and a "+" symbol. It looks like it is built in two pieces (upper and lower), so I tried to carefully remove the upper piece with needle nose pliers while leaving the lower piece connected to the circuit board. Well, the whole thing ripped out! I thought two things: 1) It will never beep again, and 2) I hope this didn't break a circuit causing the whole thing to fail.
Well, I put the circuit board back on ( I left off the one difficult screw, as 6 of 7 is more than sufficient to hold it on). Put the whole unit back together, and . . . . IT WORKS FINE!!!!!
Good luck!

    One other comment. I wouldn't exactly recommend ripping out the beeper from the circuit board like I did. I may have been extremely fortunate not to disrupt some other circuitry. I can't guarantee you that you won't damage anything. I think I just lucked out.

  • zhensman Dec 12, 2010

    Yeah, I figured by now you had long since solved it, but hopefully it will help someone else.

    I used this same approximate method on my Lasko 5395 and it worked! I found the same black ring on the top of my circuit board which I pried completely off. On my model I had no issues with getting the screws back on. I will note that there are two triangular "security" screws on the back cover of my heater, which I used normal scissors to unscrew (I don't have any fancy tools and the scissors fit well enough).

  • lucy Nov 17, 2011

    P.S. Thank you so much zhensman for the instruction.

    On a side note to others (an addition to my previous comment), I am posting this immediately after I fixed my space heater of the annoying beep (because I am so happy it still works! and w/o the beep) -- so while it seems to be working great -- I am not sure if this has affected its future longevity or quality.

  • zhensman Nov 22, 2011

    Glad it helped! As far as longevity is concerned, my "modified" Lasko is still working fine.

    Awesome post, the only one I found that provides a solution. Igive credit to you for pulling that circular black speaker out (with hole)...that was risky but has benefitted us all :) Btw I have a Barrington tower heater I bought from Walmart, took the back off (about a dozen small screws) located the circuit board at the top of the unit and UNPLUGGED mine by gently wiggling back and forth. Nothing came apart :) Thanks again for posting Z-man...super helpful.

THANK YOU!!! I did the same and it worked! I've had this heater for 2-3 years. I removed the cap by wriggling it out and it popped off with no problems.

My fiance is a light sleeper and he wakes up before 3am, so I don't want to wake him up because I'm trying to stay warm. :/

The top "control board" had screws so I removed it and it was easier you access the circuit board screws.

Thanks so much again!

THANK YOU FOR THIS! We were using the heater in our baby's room, and the loud annoying beeps would wake our baby every time we turned it on/off/adjusted the temp while he was sleeping. I have a different model of the ceramic Lasko heater, but the instructions were adequate for me to find the speaker. I did have to purchase a specialty T10 Security screwdriver (bought it from in order to remove the back of the unit and access the circuit board.

I have a older Carrier heat pump, model 38YKC060. Does anyone know how cold it will continue to work at?

Heat pumps are of little or no value at temps around 40 degrees or below. And if you use the strips it will cost a small fortune if you have relatively high electric rates as most folks do.

How do I fix my electric heater

  • sounds like the sensor or bulb that tells it to start the blower is defective/ im not familiar with your unit but this seems the most logical answer most furnace will not turn the blower on right away usually 90 seconds after the ignition but will also run longer to exhume any dangerous carbon monoxide. Electricic heaters are different. What type of unit do you have

It might have a fuse that has been blown internally. This may have happened to protect it from over heating because it was left on too long or something went bad and it got too hot.

Electric Furnace stopped running

You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

Why can't I lower my honeywell 8500 below 67 on cool?

With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed
