1.Not an expert with natural gas furnaces.
2.Statements below are from my own personal experience, and knowledge from.

The red blinking light you see is on a computer control board. The flashes of the red light represent a type of code. Think of it as a Morse Code, if you will.

For example: Red light blinks three times rapidly, pause, then blinks one more time. This code represents a particular fault. (Fault = Problem)

There is a sticker, with a chart of codes listed for this red light. It is usually placed very near the red light.

A gas furnace should be repaired by a competent HVAC technician. This is not a device that should be attended to, by those who are not trained.
An HVAC technician will know where to look, what parts are needed, and if the gas furnace is safe enough to put back on line. (Safe enough to use)

Unit won't operate and there are 4 flashes on the red light.


Two things- Clean the sensor rods or replace(cheap and easy with YouTube instruction video) and at the same time replace the main program chip (also a easy plug in chip). The whole repair takes two hours for a homeowner and costs about 50 bucks for a chip. These are easy an generally the flame sensor rod is the culprit. The code may also be the limit switch but try EZ and cheap first. See You Tube..

Atwood water heater g6a8e lights but flame goes out after 5 to 10 seconds. I replaced igniter / thermocouple and it worked for a while but problem is back. So I need to replace circuit board?


Make sure you pull connector off and clean it and contacts on board. Be sure igniter is in flame good too. Does it have the thermal cut off in-line? Its the little resistor looking piece inside the plastic cover. If it does, and still running a few seconds and going out, remove it from the circuit, and connect wire end to where you removed cut out from, thus eliminating it from the circuit, and test it. If that cures it, replace that cut-out, as it is a safety device in case of flame up, it cuts gas off to prevent fire. Just leave it out long enough to test it.

No hot water


Electric water heater can be repaired by homeowner.

Four things can cause NO hot water:
1) ECO red reset button tripped. Remove top cover on water heater, push red reset button on thermostat. Put insulation and cover back over thermostat.
2) Circuit breaker is tripped, circuit breaker bad, or wire loose in breaker box. Turn breaker on-off and listen for crackling or fizzing sound, and burned smell. Test breaker for 220Volts. Test top two screws on upper thermostat to see if water heater has electricity.
3) Bad upper thermostat. Replace upper thermostat.

4) Bad upper element. Test upper element.

Error code 76 C4 heater shuts off every 5 mins while in shower


Remove power source from the unit. If remote control2.gif is installed; remove cover and lift the control wires on the terminal...can be accomplished from either end.

Restore power and see if unit functions normally.

Contact Paloma/Rheem customer (800-432-8373) support and notify them IF you are getting a code "76" error. Rheem has recently extended the warranty on the "Burner Control Assm."; which is your problem. The C4-C8 portion of the error code, is where the unit stops the ignition process...burner fails to light, or gives you intermittent hot water. In either case, contact customer support2.gif.

If this helps, please indicate so.

Atwood. Will not light. Red light comes on and stays on.


A GOOD RV DEALER SUCH AS WHERE I WORK HAVE A BOARD TESTER AND CHECK IT FOR FREE. A DEALER NEAR YOU SHOULD BE ABLE TO DO IT FOR YOU AS WELL. THE SENSORS ARE THE ECO AND T-STAT. NO, THEY CAN'T BE BYPASSED. THE ECO AND T-STAT WORK IN CONJUNCTION BY REGULATING THE WATER TEMP AND PROVIDING POWER TO THE CIRCUIT. THEY ACT AS SAFETY DEVICES.

Electronic fire. fires up , Shuts down after 5 sec.


it sounds more like you have the ignitor wire shorting out on metal and won't allow it to stop trying to light the burner, hold the wire away from any metal and see if it helps, if this isn't the caee your circuit board needs to be replaced,

High water temp


Have you done a reset on the board?

The reset function is used to restart the Temperature Control System after an error condition has been detected and
corrected.
Reset the control by pushing the red reset button on the controller. After a reset, the control performs self diagnostics
before normal operations begin. This takes approximately 10 minutes.

Then do the following if the flashes don't stop.

1. Make sure upper and lower access doors and insulation are
properly in place
2. Check element circuits for resistance of 5 - 25 ohms
3. Replace element if necessary and reset control system

I have a digistat scr with a flashing red light and no heating there is nothing wrong with the batteries, this only occured after a poweer cut.


Try this first before condeming the unit.

1. Turn off the power supply to the Digistat SCR (receiver unit)
and leave for 5 seconds.
2. Turn on power to SCR unit and check red light is on.
3. Press override button No.2 and check the green light comes
on and boiler fires.
4. Press & hold down button No.1 (Keep depressed), then
press No.2 and keep depressed. {The Red LED light will flash
a couple of times and then it will go out}
5. Now release both the buttons – {the two LED lights should
come back on}
6. Get the Digistat+2RF/+3RF unit and stand two metres away
from the SCR unit with the Digistat+2RF/+3RF unit in your hand.
7. Remove the battery cover and fit the batteries.
8. The Red LED light on the SCR will now flash for approx. 7
seconds.
9. This confirms that the radio signal is being sent and
received.
10. The Digistat+2RF/+3RF and the SCR are now successfully
linked by a dedicated RF address.
