Question about Reddy Heater-170,000 BTU Kerosene Deluxe

Open Question

So I have a 2 reddy heater 170Ts one of the ignition control boards is bad. I am looking to repair the board. If I use the bad ignition control board in the the heater it will wait about 30 seconds and then the fan and the igniter will come on but will compleyelt shutdown after about 30 more seconds. If I cut it off and cut it back off it will do the same thing. If I use the known good board when I flick the ON switch it will immediatly cut on the fan will spin and it the igniter will start glowing and will not cut off until I press the switch.

SOURCE: r100 reddy heater, low pressure forced air heater.

The R100 is a kerosene heater and the RLP100 is a propane heater so I am not sure when one you have.
If it is kerosene then you may need to check the pump pressure. Also the Safety swith can give you a cut out after 30 seconds.

If the unit is Propane then you could have a bad control board or a flame sensor.

You can call our service department at 1-800-475-5660

Heater will not ignite when plugged in fan will run it trys to light i think its not getting any fuel to light when fan stops heater shows E 1 on the gauge

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 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.

R100 reddy heater, low pressure forced air heater. the heater ignites, motor runs for 30 seconds then shuts down. photo cell good, filters clean, no ignition board, pump pressure unknown.

The R100 is a kerosene heater and the RLP100 is a propane heater so I am not sure when one you have.
If it is kerosene then you may need to check the pump pressure. Also the Safety swith can give you a cut out after 30 seconds.

If the unit is Propane then you could have a bad control board or a flame sensor.

Will not ignite fan runs

Take the cover off, if its anewer one it is probably a glow coil ignitor.
Plug unit in, if it does not glow then either the control board where the
ignitor terminals plug in are bad or the ignitor is bad.

You can either apply 120volts directly through the ignitor leads if you
are electrically inclined and see if it lites up. If it does then part of the
board is bad. However you can tie into line 1 and nuetral and not use
ignitor terminals on the circuit board.

If you need a replacement ignitor you will have a hard time finding one,however I used a White Rodgers 21D64-2 Universal Ignitor Kit
that I got from Johnstone Heating and Cooling Supply Company.
My heater was only 3-5yrs old.

Reddi heater 155 owners manual?

If this has a hot surface igniter, can you see it glowing? If not the igniter could be bad or the control
board for the igniter is baed.

If you are able, remover the igniter and hook it up to a 110 outlet, if it glows the problem is in the board.

If it has a board, follow the incoming power to line 1
and line 2. You will either have to splice the two leads
from the igniter into L1 and L2 or get a special spade
connector that can hold two leads on each terminal.

Plug unit in, glow coil should glow and unit should run
thats assuming you have that style of unit. Do not
attempt to do this unless you can safely perform this.

If you know of an electrician he can do this.

Ive got a reddy heater pro 155 when you turn it on it runs rich burns youre eyes fumes i took it to a man that works on them here local and he said the board that controls fuel mixture was bad what do you...

Are you sure it is running too rich? Your eyes will also burn if it runs too lean because the hyrocarbon and nitrous oxide balance is off. If too rich, there usually is a smokey vapor that is emited, whereas too lean does not create any seeable vapor.
If youhave a little tech to you, you can over-ride the control board and have the power go directly to the burner (as is in the older burner models). If you get the same results, then you'll know itis not the control board. Goodluck,Macgivor

R60 6o,ooo

Your problem could be as simple as a blown fuse. Most R60's have a small buss fuse mounted on the Ignition Control Board. Replacement fuses are available at . If the fuse checks OK then test to see if the control board is receiving power. If power is going in but not going out then, naturally the board is defective and must be replaced. An easy fix!

Ignition problems

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.
