20 Most Recent Reddy Karosene / Desel Forced Air Heater w/Wheels Questions & Answers

The heater has a photocell & control board. The safety system is not allowing the heater to run because ALL systems are not functioning properly. The control board shuts the heater down after 5 seconds if the system is not operating at 100%. Most of the time the problem is a simple adjustment, but don't adjust anything without knowing EXACTLY what you are doing.

Suggestion- If you are going to do a DIY repair then send ReddyParts.com an email, request troubleshooting tips for the HSI type heater. Be sure to send correct model of your heater. Without the correct model you may not get a reply.

You don't give your model, so I can only assume that you have one of the TA Models.
C2=high voltage.

Assuming the "electronic safety shutdown system" is operating properly, the system is shutting the heater down becausr the control board/photocell don't like what is being seen inside the combustion chamber. That is what they are supposed to do if there is water, trash, an air leak, a vacuum leak, a broken ignitor, a worn nozzle, etc.

Your job, as the troubleshooter, is to find out why the flame is not correct. Read the tips below:

Good luck!

First, locate the true model of the heater. Pro 155 only designates a series of heaters. It does not designate the actual model or technology used.

The reset (Safety Device) is the system's safety shut off. If everything is in perfect operating form the photocell looks into the chamber for a flame. If the flame goes out (flame-out), the the photocell sends a signal to the reset and the heater shuts down.

You must troubleshoot to find out whether your problem is a fuel delivery problem or an electronics problem.

My first look would be to look into the eye of the photocell for an insect or nest of some sort. Next check the fuel tank for water or debris that may be restricting the fuel flow and causing a flame-out.

You have fuel and spark but it won't ignite...
The problem must either be the spark or the fuel - the ignition unit isn't an unusual failure so is the spark gap correct; if there is a failing spark there is a temptation to reduce the size of the spark gap.

The fuel, paraffin or diesel isn't very volatile so it must be presented to the spark in a form that is easily burned and that means a very finely atomised spray - problems with the spray are common with older heaters, usually caused by small particles of dirt or rust either making the spinner stick or freeze or wearing the fit between the spinner and jet and the jet orifice and even if the jet is in good condition it is important to have the correct air pressure that is checked and adjusted whenever the heater is serviced.

Paraffin or kerosene has a fairly high content of dissolved water and when the inside of a fuel tank is unprotected steel, the fuel can cause some rusting...
A thorough internal clean and refill with filtered fuel will usually restore performance for the season.

Apparently the photocell needs to see a flame of the correct colour or it will shut down so the nozzle and spinner has to be in very good condition - diesel might be clean but is the inside of the tank clean?
The fit between the spinner and nozzle is so very close it can stick with very small particles.

Can't speak for the Reddy Heater but a bad spark transformer seems a very common problem with that type of heater - ensure the spark gap is correct.

After 19 years of service, your Reddy heater probably is ready for replacement.

Never try and light a furnace when you have a glow coil ignitor. Even if you managed to do so it would reach high temp and limit would stop it. . trained technician can do this but why? If your glow coil is glowing constantly after start up than mast likely you have a control board problem. Call a technician to troubleshoot it
