Question about RTO Comfort Zone Electric Portable Space Infrared 1500-watt Heater

Open Question

Robeson heaters I have a Robeson model 03-2701 portable electric space heater ( fan forced heater / humidifier.) When I use the machine, I note that the portion of the power cord nearest to the electric wall circuit (where I plug it in), becomes very hot to the touch after limited usage. There is no fraying or tearing or cracks in the insulation material around the power cord. So, why is it heating up and what should I do ?

I am assuming that this is an electric unit? The heating elements could be bad. I would contact the manufacturer for a service manual for your unit. There you will find instructions on how you might be able to reset the unit if possible. One thing you can try is to shut all power down to the unit and then restart. Also check for any "reset" switches on it as well.

SOURCE: Hot water heater is not working correctly on electric

Check that the by-pass valve(s) on or near back of water heater are in the proper position. If your stumped on how they should be for normal operation, remember this. Cold water has to flow into bottom of tank, so that valve needs to be open straight into that fitting. Then the hot comes out the top, so that valve has to be open as well. Any valves in between those lines need to be closed, otherwise it will mix cold and hot . If still not sure, get back to me, with location of any valves there, and I'll guide you through it.

SOURCE: My water heater on electric is not heating to full

Most electric water heaters have 2 heating elements. The symptoms you're describing indicate that one of the elements has burned out and needs to be replaced. If you want to try to change it yourself you can contact me back through and I can try to explain how to do it.

SOURCE: cracked water heater

Clean the crack up and expose clean metal by sanding it or a small grinder. Use JB weld it is a two part mixture that set's up hard as steel. Any hardware store should carry it.
I have fixed gas tanks,glasses and a few other thing's with it.
The main thing the surface has to be clean so the compound get's a grip to the metal. Since you already have a crack the compound will go into crack to get a inside bond.
You may use a small file or sand paper to open up the crack a little by adding a bevel to groove to expose shinning metal to get acurate bond.
Drain tank and let it dry out before attemping to fix.

They make all kind's of JB weld for different types of applications and Lowes or Home Depot will carry it.

My 40-FAC heater will not ignite and run. The igniter has been replaced. What should I check next?

These models require electrical power to run the blower fan.
When you connect the electrical cord, the fan should turn on, then you should be able to start / ignite the propane. if the fan does not turn on when you connect the power cord, you will not be able to ignite the propane.
