• The low-pressure switch senses the refrigerant pressure in the sealed refrigeration system to protect

against certain conditions that could be detrimental to compressor life. The switch turns the heat

pump off in the event of loss of refrigerant, fan motor failure, evaporator freeze-up, or airflow

blockage. The heat pump will automatically reset the switch after the system pressure rises to the
normal operating pressure. The display will show "LP", if this switch is tripped.

For more info, look at page 7 on this manual:

http://www.hayward-pool.com/pdf/manuals/Manual280.pdf

Either you need to defrost the coils, clean the air-flow chamber, get a new air-flow switch or you are running low on refridgerant.

Repeated 3 flash on power vented honeywell gas control thermostat means system in lockout.

Repeated 3 flash on atmospheric-vent Honeywell gas control valve means temperature sensor failure.
Take apart gas control, and buy temperature sensor if sold separately at AO Smith dealer.

Richmond power vent 2 flashes code 4-4


Sounds like a pressure switch or simular sensing device that is not proving positive, thus a possible vent blockage or defective sensing device.

My Norcold N611 frig code flashes 3 time every few second and doesn't go into A/C mode and will only go into gas mode when the switch is in auto mode and the interior light stays on even when the


The N611 will flash 3 times as an AC heater fault. If your AC heaters are ohming out properly (48 ohms of resistance), then you have a bad power board. If the AC heaters are not showing around 48 ohms of resistance, replace the AC heater. It's going to be one of the two. Here is an article on it:

Rheem model 41vrp40n flashes twice and stops working


Error code means that you have electronic gas control valve.

Copy following link to identify gas control valve, read error code meanings for each, and download service manual relevant to each gas control, but not specifically Rheem since rheem does not post service manuals.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

The fact that water heater restarts, means that water heater is getting gas, getting sufficient air for combustion, thermister is ok, gas pressure is good, etc.
The fact that you unplug and replug water heater and it works, shows that you have power vent model.
Since water heater worked correctly before, 2 flashes with Rheem power vent model could mean that pressure switch has failed.

Power OK, can smell gas, but no ignition. Get the


The EO4 is listed as a Fan Failure. However, these heaters have a tendency to go EO4 for no apparent reason. It is what I call the "heater hic-cupping". The easiest thing to try first is to reset the heaters computer. To do this, you will open the right hand side door, find the POWER toggle switch and move it to OFF. Then turn off the Circuit Breaker to the heater,shutting down all electrical power to the unit. You will need to wait about 15 to 20 minutes before you do anything else.

After that time, revese the order. Turn on the Circuit Breaker, then the Power Switch on the heater. Try and start the heater. The computer will "reboot" flashing codes like --- or 888, do not worry about those. When the display panel comes back to normal, check what the heater is reading for a water temp and compare that to what the water is actually. Hopefully, they will be right on, or close, together. The heater will try to start 3 times before going into "Lock Out" mode.

If it does start, it was just the computer hic-cupping. If it does not start and you receive another EO code, on the backside of the Display Panel, there are Diagnostic Lights. If there is a light on by a couple of letters, like HLS or PS, then that is what is malfunctioning.
