Raypak RP2100 266k BTU Millivolt Pool Heater - Propane Questions & Answers
My Raypak RP2100 heater, when starting for first time of the day, shows CFH, then SPK and then just buzzes.
The error codes and buzzing sound you are experiencing with your Raypak RP2100 heater indicate potential issues with the ignition and flame sensing components. Here are some troubleshooting steps you can take:
1. Check Gas Supply: Ensure that there is an adequate supply of gas to the heater. Make sure the gas valve is fully open and that there are no obstructions or leaks in the gas line.
2. Inspect Ignition System: The CFH (Call For Heat) and SPK (Spark Ignition) codes suggest that the heater is having trouble igniting. Inspect the ignition system components, including the spark electrode, ignition control module, and wiring connections. Clean any debris or corrosion that may be affecting the spark ignition.
3. Check Flame Sensor: The buzzing sound you hear could be related to the flame sensing system. The heater may not sense the presence of a flame, causing it to shut down. Inspect the flame sensor for any buildup of soot, debris, or corrosion. Clean the flame sensor using a soft cloth or a non-abrasive brush.
4. Verify Proper Ventilation: Ensure that the heater's venting system is clear of any blockages. Blocked vents can lead to incomplete combustion and affect the heater's ignition process.
5. Consult the Owner's Manual: Refer to the owner's manual for your specific model of the Raypak RP2100 heater. It may provide additional troubleshooting steps and error code explanations that are specific to your unit.
6. Seek Professional Assistance: If the issue persists or you are unable to resolve it on your own, it's recommended to contact a professional technician who is experienced with Raypak heaters. They will have the expertise to diagnose and repair any complex issues with the ignition system.
Remember, dealing with gas appliances can be dangerous. If you are not experienced with working on gas heaters, it is best to contact a qualified professional to ensure proper troubleshooting and repairs.
I have a Raypak 399L and the LCD screen shows Spa Set 100F. Under that it says sensor failure. It wont start up
It sounds like there may be a problem with the temperature sensor on your Raypak 399L spa heater. The "sensor failure" message indicates that the heater is not able to detect the temperature of the water in the spa. This can prevent the heater from starting up and operating properly.
Here are a few things you can try to troubleshoot the issue:
- Check the wiring: Make sure all of the wiring is securely connected and there are no loose wires or damaged connections.
- Check the temperature sensor: The temperature sensor is typically located in the heater itself. Make sure it is securely fastened and there are no visible signs of damage.
- Test the temperature sensor: Some models of the Raypak 399L have a diagnostic feature that allows you to test the temperature sensor. Consult your owner's manual or a service manual for instructions on how to do this.
- Replace the temperature sensor: If the temperature sensor appears to be damaged or is not functioning properly, you may need to replace it. This will typically require the help of a qualified service technician.
I hope this information is helpful. If you have any further questions or need additional assistance, don't hesitate to ask.
Raypak Pool Heater wont stay ignited
Hi,
Please be careful when dealing with products using gas. Double check that the area around where ignition occurs does not have air blocked off as low oxygen would stop fire from occurring. You can also check fuel level of machine. Thank you.
My raypak 406 btu is making a howling sound during operation. Any ideas? Pool heater
This is very common with Raypak. What you hear is the way the air flow drafts through the heater. Raypaks typically draft very well. The rise of the heat off the burners draws in fresh air at the bottom and sides of the heater through the louvers and expels out the top.
You need the right mixture of fuel and oxygen for efficient burn and proper draft. A week flame or inefficient fresh air and the heater will not draft properly. A 406 is a very big heater my initial reaction is to check the gas supply. My assumption is the gas line may be undersized, especially if this heater was recently installed in place of a smaller unit. If the gas line is undersized the heater may operate but in time the insides will soot like a chimney and also change the dynamics of the way it drafts. Soot can also be a fire hazard so it is worth having a professional take gas pressure readings.
