Dimplex Fireplace - Fan?

It got a bit chilly this morning. So we thought we'd try out the fireplace. Not much heat coming out. Checked the operation. A small amount of heat comes out of the top but I don't hear a fan. Then the heat stops but the "fireplace" appearance below continues to glow.

Reading other users comments - the heater helps "keep the chill off". The fireplace looks good BUT almost zero heat.

Is this normal operation?

Thanks.

We use our Dimplex fireplace regularly and the fan operation on ours is silent. A small amount of warm air is expelled from the top of the unit but not enough to quickly warm an entire coach. It does take the chill off but it does it slowly.

Thanks all - let me describe what mine is doing.

Switches set up as described in manual.

-Far right hand switch is to enable remote. I set it to remote.
-Middle rocker switch is set so the left hand side of switch is down.
-Rotating thumb switch is set entirely as far as possible clockwise.

It took me a few tries to figure out which switch is which and how to set them. The unit does glow red in the upper center for a few moments but after about 5 seconds - stops glowing. I presume this is the heating element.

I believe I have the settings correct and that the unit is shutting off to prevent overheating.

Comments - other inputs?

Thanks again.

The thermal limit switch went bad on my fireplace two weeks ago and I had to replace it. Since we travel around the country full time I and we couldn't wait for a dealer to do the warranty work I had Dimplex overnight the part to me. It turns out that the heater, blower and thermostat are an integral unit that you can see if you look through the opening next to the control switches. If your unit is shutting down then the thermal switch is probably the culprit. If it's under warranty Dimplex can send a replacement or they may sell you one if not still under warranty. Replacing the heater/blower assembly is actually quite straightforward.

We use the furnace to get the temp up when it's cold, then switch it off and turn the fireplace on, it will keep things very cozy all night even in 35 degree weather. We have a 5th wheel with dual pane windows which might make a difference, since the warm air rises.

JEdgar - couldn't agree more. I contacted Thor Warranty and they have opted to have an authorized technician do the repairs. So I drive the unit to my trusty warranty support team and leave the unit with them. Pain in the neck for me but a bigger pain in the wallet for Thor. Their choice.

Also, I can get the control panel fixed- someone during assembly glued srews in to hold various switches. This glue breaks down and the switch fall back into the panel. I did a temp fix by drilling and using the previously screws to more firmly attacheds the switches.

Thanks to all of you.

We had the heater element go bad on our last trip. Heated for about 5 seconds and quit, just like you describe. Wife called Dimplex who diagnosed the problem as a heater element. Mailed us one for about $85. We installed it and it works fine again. Install was tricking figuring out how to disconnect the wires. Take a picture of what connects to what before starting. Use a flathead screwdriver to pry them loose.

On ours the heater assembly is seperate from the thermostat, unlike what someone said above. We didn't need to replace the thermostat.

in our previous 5'er we would use it as a main heat source it was so efficient !

BUT, we are in the sowth, so cold temps is a relative term

Our fan motor started making noise and it was an easy replacement once I figured out HOW to get to it
