Default Electric Heater Cleaning - Be Not Afraid!

Hi folks,

I finally got up the gumption to clean the forward heater located in the center console. I had read a while back about a possible fire hazard from built up debris coming into contact with the heater wires. My front heater started to temporarily turn off and the overheat light come on. I figured that debris buildup was causing this.

So, I dug in and started to see how to get at the heater unit. I took the two bottom drawers out that were directly above the heater unit. I saw and removed four screws that were securing the wood frame insert that holds the drawers. This gave me complete access to the heater unit. Several more screws removed and the heater was loose except for the power wires which I left attached.

I removed two screws to get the cover removed revealing all the guts of the heater. Wow, the heater was absolutely full of debris, not good!!! I looked from the front at the heater wires and saw sponge material just behind the wires. Well that "sponge" was actually a thick mat of debris built up thus impeding the free flow of air across the heater wires. I was unable to vacuum that debris out so I blew it out with compressed air. It came out in mats along with a lot of airborne junk. Might want to have a mask on when you do this.

After a thorough compressed air treatment and vacuuming with the brush attachment, it looked nice and clean. Quickly reinstalled everything and the heater works like a charm and works much better than it did before. No more overheating and much more heat output. Most importantly, any fire risk has been minimized.

Since this was my first time exploring and figuring it out, it took me about an hour from start to finish. Could do it again in 30 minutes knowing how it all goes together. Well worth the minimal effort and time to get it done. I hope that reading this will encourage others to give it a look and clean it out. It is no big deal and I am an extreme novice at the DIY stuff. You can do it!!!

Hi Jerry-

Good job on cleaning that toe kick heater--it's looks better than new!

There are some other threads on this subject that describe the fire danger and subsequent recall of the original equipment heaters, and I replaced mine last year for approximately $100-150 each. The way you can tell the difference is that the older units have the very fine wires like those shown in your photos, and these wires can apparently achieve ignition if they get as clogged up as yours were.

Since these heaters have been recalled for their potential fire hazard you might want to consider replacing them with the drop-in replacements that are available (I believe I got mine through Amazon). The newer ones have a heating tube with a larger surface area that can't get as hot as the fine wires can, thus reducing/eliminating the fire hazard from lint and debris.

I just did mine this week, I will open them up and take pictures. My units have a little 5 inch fan with 5 blades rather than the squirrel cage. Also there are 4 individual round tubular heating elements, however only three are connected so it is set up for 1000 watts. The control has a bulb type thermostat that moves the actuator toward or away from the micro switch that energizes the unit based on the internal temperature of the case. It actually switches off if I hold the bulb in my hot little hand.

Our 88FC is the same as Gardner's pictures, heavy duty heater elements,
They can also be rewired for several different heat ranges.
I decreased the bedroom heater and increased the kitchen heat range.
I think the choices are 500, 1000, 1500, or 2000 Watts.
This also helps balance the leg loads, depending on personal usage.

Bill,
You are too fast. I added a line about the element hookup. Here is the chart, note it says to DISCONNECT the indicated leads for the listed wattage. It begins with all leads connected. There are no leads on the 5-6 element on either of my heaters, so I assume BB cut them off. That makes them 1500 watt units.
