Check the fan cage on the back, it should be cleaned to allow for adequate air flow. Be sure curtains are not getting pulled up to the fan cage.
This could also be due to a crack in the pot, or if you put too much fuel treatment in your fuel. Regardless of what is causing the overheat situation, an L 72 is a very old unit. You may not want to invest a great deal of money into repairing this unit. The manufacturer has discontinued several parts for the L 72 such as the main circuit board and the burner rings. Without these parts, you are out a heater.
If you can clean the fan cage and remedy the problem, that would be great. If it is a cracked pot, and you decide to replace, be sure that you know how long it has been since you replaced the ring. A ring in a Laser lasts about 7 years. If your technician does not have rings in stock, you could be out of luck when your unit needs a ring.
Be sure to plug the unit into a dedicated outlet and use a quality surge protector with at least 450 Joules to help protect the board. Hope this was of some help. If you have any further questions, visit www.keepuswarm.com. We do have inventory of these discontinued parts for Laser heaters if you decide to repair and your technician cannot get the needed parts.

The fan's power comes from a multi output transformer.
Either the fan is burned out or the transformer is burned out or the fans moles plug is not plugged in properly.A simple voltage spike or brownout can take out the transformers.

I would recomend having a qualified technican service your Toyo.

It IS possible to clean it yourself, but you will want to do it during a time that you aren't needing the heater to keep the space warm.

Certain parts can be hard to tell if they are working as they should if you aren't familar with what you're looking at.

With proper service, your Toyo will operate efficently, and likely last for a long time.

Remove front grille by taking out two screws at lower right and left front sides of stove. slightly pull botom front of grille toward you and lift up and off. Look for two red wires going into burner chamber, the wires will be incased in a gray plastic sheath as they enter chamber. Push on buton like you are trying to start the heater. While it is going through start up process hold the gray plastic sheath with two fingers and see if the sheath does not get warm in a short period of time the igniter is bad and will need to be replaced. This can be cause by water getting into the burner chamber and causing the igniter to crack.

If you have too much fuel in the burn pot then you are getting no ignition. Repeated tries to get it to start just dumps more fuel into the pot.

If you are talking about between the outside and the gray flex pipe, remove the pipe and blow the stuff back outside. If it is beyond the gray flex pipe, then a disassembly will be necessary.
To prevent further entrance of anything, debris / bugs to either the intake or exhaust, see my modification to the intake/exhaust pipe here: Thread Toyostove Exhaust Bug Shield .

I would suggest that you make a special box for it but it entails a lot work right? I might as well recommend that you browse E Corrugated. They have a wide range of boxes and cases for shipping. You may find something there that suits your requirements. They are a manufacturer of boxes and cases specially designed for shipping whether overseas or locally. You can talk to a staff of the company with your requirements and surely they will have something for you. You also label your box with 'upside down' and 'handle with care' or 'fragile' to ensure that the carriers will know it and ensure that your package is in good hands. Talk to the carrier about it and know how they ship it without being damaged.

Could be orange for a few reasons could just be burning some dust or something in the air. if it keeps staying orange i would say that it has a cracked heat exchanger and the fan is disrupting the flame.
