20 Most Recent Reddy REDR40T Heater Questions & Answers

spamcatcher1,

All these type heaters (Reddy, All Pro and Master heat) were made by DESA international.

I have a tip at http://www.fixya.com/support/r4124129-yearly_maintenance_reddy_heaters which explains this common problem, where to get the repair parts and how to do the repair.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

I had a similar model and the thermostat should be located on the side or back of the unit. however, if you hear the fan kick on and it doesn't light, it sounds like an issue with the ignitor, which lights the flame. You can go to Reddy's website for a support such as schematics, troubleshooting and replacement parts.

Even though you have fuel do you have fuel pressure? I would first check the filters. If the output filter is dirty it will spit out fuel but not build pressure to properly atomize the fuel.

Hi,

Here are a couple of tips that I wrote that tell you how to troubleshoot a Torpedo or Reddy heater...

Try the link below. You can run down the list of checks and also get parts. You need to repalce the nozzle or clean it yearly. If it's older replace plug too. Check pump pressure.

Remove the top of the heater and turn it on. Look for the igniter to start sparking if it uses the spark plug type igniter or if it uses a HSI type, look for it to start glowing. Next, use a flashlight to look for fuel spraying out of the nozzle. If it isn't check the nozzle for a clog. Check the fuel filter. Remove the filter cover on the back of the motor and check the air filter. If this doesn't get the fuel going you will need to get a pressure guage to screw into the left hole in the filter cover and check the air pressure going to the fuel nozzle. It should ~3.5#. You can adjust it by turning the adjusting screw in the other hole in the filter cover. That plug should have a hole in it.

I definitely would check the thermocouple. You can try cleaning it up with steel wool and position it as close to top center of the pilot as this is the hottest part of the flame. Also while you are at it check to see that it is screwed in tight, they will not work correctly if they are loose. Do not crank on it but make sure it is snug and just a little crack beyond. If this does not work replace it with the correct thermocouple and happy heating.

Patience here is everything and you have some trouble shooting to do.Remove the cover and locate the igniter, now carefully trace the wiring backwards to the power source. There may be an in line fuse that blew when the old igniter went out. You are also looking for loose or disconnected wires, it is not unusual to have a wire connector come loose because of a bad crimp, cold solder joint or even faulty wire nut not grabbing the wires tight enough. The shut down is from the flame sensor it is a required safety on these heaters so that is a good thing and is working correctly.

www.reddyparts.com lists the R40T as using the ignitor PP200.

Sounds like the nozzle is clogged or malfunctioning causing to much fuel to be burned thus giving off too much smoke. 1st thing is to pull off the top cover held down by 8 or so 5/16 bolts once removed you will see the nozzle you may be able to take it off and clean it. but i dont think there that expensive. Also maybe replace the fuel filter if applicable, you will see it inline before the nozzle. good luck

Here are some possible causes and solutions: Insufficient fuel supply: If the fuel supply is not sufficient, the heater may shut off. Check the fuel tank and make sure it is full. If the fuel tank is full, check the fuel line for any blockages or leaks. If you find any issues, repair or replace the fuel line. Dirty fuel filter: A dirty fuel filter can cause the heater to shut off. Check the fuel filter and clean or replace it if necessary. Faulty photocell: The photocell is responsible for detecting the flame. If the photocell is dirty or faulty, the heater may shut off. Clean the photocell with a soft cloth and check if the heater works properly. If the problem persists, replace the photocell. Defective motor: If the motor is defective, the heater may shut off. Check the motor and replace it if necessary. Broken ignition system: If the ignition system is broken, the heater may shut off. Check the ignition system and replace it if necessary. As you have covered some other possibilities, if the above doesn't offer relief, you may have to consult a professional technician or contact the manufacturer.

Yes Don, 3 to 4 thousandths of an inch is correct. http://www.bealsmotor.com/Desa%20Hot%20Surface%20Manual.pdf

Based on the information provided, it sounds like you have done a thorough job of troubleshooting and replacing various components of the heater. Since you are unable to get more than 2 psi out of the pump, and the pressure adjustment screw is maxed out and does not seem to change the pressure, the next step would be to check for air leaks. One way to do this is to use a soapy water solution to check for bubbles around the pump and other areas where the air lines are connected. If a leak is found, it should be repaired or replaced. Additionally, it's also worth checking the condition of the pump diaphragm and reed valves to see if they are worn or damaged. If they are, they will need to be replaced. If the problem persists, it may be necessary to consider replacing the entire pump.

Question edited for maker name. Troubleshooting videos https://www.google.com/search?q=reddy+heater+170t+will+not+start ..

dry bearings or bushings going bad

here is link to video, that will help you. If photo cell does not see the flame unit will not work https://www.youtube.com/watch?v=nEVoUIfJraM

Sounds like the new photocell is bad or you don't have the right one

if smells like gas dont use and check for leak

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.
