20 Most Recent Reddy R155D Utility Heater - Page 3 Questions & Answers

There should be some sort of fire eye on this, either a visually operated sensor of a thermocouple that is reading the temperature of the flame. If it senses no flame it will shut the unit off so you don't get poisened by fumes.Does it re-set when you try and start it again or do you have to push the reset button, either way it needs to be re-set before operating again. I suspect that this sensor is causing your problems. These units also have fuel pumps, this may also cause the problem, hard for me to tell without seeing the unit.

You wrote "Is R155D the same as PRO155 ?" Answer- Yes, The R155D is a pro 155, BUT so are many other 155's and not all use the same technology. The newer ones are computerized, the older ones are not.

Yours, the R155D is computerized and uses HSI (hot surface ignitor) technology.

Filters....part number PP214 (complete filter kit).

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

Reddy Heater - Troubleshooting Torpedo Heaters Torpedo Heater Pump Pressure Adjustment

Possibilities:

1. Water in fuel
2. low fuel
3. Incorrect air pump pressure
4. Restricted fuel flow
5. Air loss between the pump & the nozzle
6. Vacuum loss between the tank & nozzle

The heater runs for a few minutes and quits. You must find out whether the problem is fuel related or electronics related. Judging by your brief description of the problem you have a fuel delivery problem of some sort and since the heater is on you bench you must troubleshoot it. The procedure is simple but you will need to borrow a "low pressure gauge" from a friend. These heaters are very particular to having the correct air pressure setting. And that statement is no BS!

This motor does have a capacitor but it is wired in series on the black leads of the motor.
You can get the complete motor for $90.00 at MS Service but I am not sure if they carry the capacitor.

You could ask the technical service and see if they have it.

This is the most common problem with these units after they get several years old. I have a tip which explains exactly how to correct this and where to get the parts you will need. I recommend getting the gauge as you will need it in the future. Go to http://www.fixya.com/support/r4124129-yearly_maintenance_reddy_heaters Let me know if you need anymore help.

I would say draining the fuel and replacing with fresh would be a good start. If you go to http://www.fixya.com/support/r4124129-yearly_maintenance_reddy_heaters you will find a tip I wrote to explain how to repair reddy heaters, where to get the parts you need and other helpful tips. Let me know how you make out and if you need anymore help.

Remove the top shell of the unit, see if the glow coil
tries to light up, if it doesnt you either have a bad outlet connection or the glow coil is broke

most likey the capacitor of the motor is bad..its like a voltage booster to get motor up in running without help...locate it ohm it out to test..if under rating change it out

Is the ignitor working? If not, make sure the gap is within 1/2 in of spay nozzle

sounds like an overload. check fan to see if it spins freely, and check motor leads with an ohm meter.

Hi, when a circuit trips that quik, it indicates a dead short somewhere or even a motor drawing way to much amps for the breaker to handle. If this heater is a forced air type, try and find the wiring that controls the blower motor and disconnect it for just a few minutes to test it. You may want to do this with other control componants one at a time, just by- pass each one by unplugging or disconnecting each one and start it. If the breaker holds when you do this, you will then know which part is causing the breaker to trip. Keep me posted on your progress.

Check that igniter is not soot covered and/or corroeded, CHeck fuel filter screen in tank to make sure it is not clogged and you are getting all the fuel needed.

This sounds like you should get a grade of an Dt.. (youre flunking, but youre doing good) This needs a good full services(change thevanes in the back of the fan motor or pump.

Did you try eBay?

The cosyglow heaters have 2 thermocouples in series to sense flame and keep the thing going. If either of them is split, cracked, or even dirty, it will not stay alight. Get it serviced/checked out by qualified people.

915 EST. lets talk

what kind of ignition is it? spark or hot surface igniter? the photocell just detects the flame. it causes the controller to go into lockout if it doesn't detect a flame. a hot surface igniter uses 120 volts to operate, again off the controller.
