Question about Lasko 5365 Ceramic Compact Heater

1 Answer

The thermostat does register the right temperature.

It ends it heating the room way way above the 68-69 degrees I set it to. Its as if the thermostat stops working until finally it stops when the room has heated up to a blistering 74-75. Setting the thermostat lower does not help since the malfunctioning happens only when the heater is on. I tried two of these things. Is there something I can do?

I have a williams thermostart . It was off yesterday . today when i tried to start its not getting started . Can you please let me know how i can start it manually using ignition . its pretty cold today


Couple of quick questions: Is the pilot lit and the Control Knob turned to the ON position?
If not, turn it to the ON position.

Has the thermostat been set higher than the ambient room temperature?
If not, set the temperature at least 10 degrees higher than the ambient room temp and see it the burner lights?

Have you checked the outside vent, to make sure it's unobstructed?

If all above the above fails to provide a yes answer, then I suspect that the Thermopile has gone bad. The Thermopile generates milli-volts of electricity that opens the gas valve when your thermostat calls for heat. The heat from the pilot flame against the Thermoplie is what generates the milli-volts of electricity.

They are not difficult to replace and only requires a screw driver and an appropriately sized open end wrench to accomplish the task. You can probably order the part directly from Williams. Also, if you have misplaced your Owners Manual, ask them for one of those too. It will be of help to you now and in the future.

Hope this helps solve your problem.

How do I Set the Thermostat Anticipator


If you have an older thermostat that has a heat anticipator in it then there are some things that you need to know about setting it and what it actually does.

First the function of the heat anticipator is to fake the thermostat into feeling the room temperature as hotter than it really is. The heat anticipator is actually a variable output heater inside your thermostat. The amount of heat that it actually produces is very, very small. This heat does, however, make a difference in how the room temperature feels to your thermostat.

If no extra heat is made inside the thermostat it will not react quickly enough to shut off the heating source. This will make the room “overshoot” the set point of the thermostat.
By heating the thermostat up very slightly it then shuts down the furnace or heat source before it actually reaches the temperature set point. This will allow the left over heat to go into the room and raise the temperature to the set point by the time it is all used up.

If you are experiencing wild temperature swings or the room temperatures are either not getting to the set point or going over the set point then the heat anticipator either is not adjusted right or it is burnt out and not working at all.

There are a couple of different types of heat anticipators. They will usually look like one of these.

If your heating is running too long then you will need to adjust the setting to a lower number. If you are not getting enough heat then go to a higher number. All you are changing when you do this is the amount of the heat coil you are using. Make small adjustments to the anticipator and then give it at least a half day before making more adjustments. Small changes can have a big effect if the heat anticipator is working correctly.

You also can set the anticipator by checking the current draw of the system. To do this you need to use an amp meter and measure the current draw of the heating unit when it is running. Then set the heat anticipator to the corresponding number of the current draw. This will at least get you a good starting point and some fine small adjustment can be made from there.

For more advanced digital thermostats there are cycle change features that do what this heat anticipator does in older thermostats. These often incorporate many things in determining the cycle length of the heating. These thermostats will not have a heat anticipator setting.

Like many things when it comes to your comfort, all people feel things a bit differently. You need to make the changes to the thermostat so that YOU feel comfortable. There is no right way it has to be done. Make it work for you and adjust the thermostat so that you are the most comfortable!

The heater will not kick on. It's a programable 7 day that reads 69 degrees and if I arrow up to 72 degrees, nothing happens


Change Temperature Setting Until the Next Program Period (Temporary Change)
? Press UP Arrow or DOWN Arrow until the screen shows the desired temperature setting.
NOTE: The temporary temperature setting is displayed for about 3 seconds and then the room temperature is displayed.
Temporary appears in the display. The setting cancels when the next program period starts or when
you press RUN PROGRAM.

Change Temperature Setting Indefinitely (Hold)
? Move the System switch to the desired position (Heat or Cool).
? Press HOLD TEMP then UP Arrow or Down Arrow to change your setting if desired. (The display changes from showing the setpoint
temperature to room temperature after approximately three seconds).
? To cancel Hold press RUN PROGRAM.


The downloadable manuals for this t-stat are here, and the addendum, here. Page 17 and 18 detail thermostat operation I have copied above. It has graphic representations of keys that do not copy over very well, so if you have questions about the steps above, you should view the manual in the links provided above.

I hope this helps! Please take a moment to rate my reply - thanks!

I have to play with thermostat to get my heating system on


You did not make it clear if the thermostat is a programmable unit or not. I am wondering if the thermostat is not set on the correct heat anticipation setting. A heat anticipater is a small heater that helps the thermostat turn off before it over shoots the desired temperature setting. If the thermostat is set for a 5 degree setting, it will turn off at 63 degrees if set at 68. If the anticipater was set at 1 or 2 degrees, it will shut off the heater at 66 or 67. Newer thermostats will only allow the thermostat to cycle 6 times per hour so if you never reach the desired temp, you have to wait 10 minutes before it will allow a call for heat. Check the installation instructions to see if there is a setting where you can get the anticipator temperature closer to your set temp. Good luck.

Heat pump auxiliary heat does not turn on


Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

Dayton G73 electric heater


I just got my G73.  It comes with a new note that says "below 50 degrees the fan will cycle randomly (and might seem like its not working correctly) but once it is above 50 it will cycle normally."  it uses that to let the element re-heat quickly to bring the room up to temp faster.

Sounds like a thermostat problem or a short in the wire. Can you give us more info like is it gas or electric and model numbers will help.
