Expert Answers about Heaters


  • Kat's Heaters Custom Fit Engine Block Heater # KH11812 Not Fitting on a 2.4L Engine for 2014 Journey
  • First be sure the Kat's Heaters Custom Fit Engine Block Heater # KH11812 you received is the correct part as I have seen times where the wrong heater was shipped or possibly returned with and placed in the wrong box. The tag on the heater should corelate to the box for the heater. Next I do see there is a slot and groves on the heater which you will want to verify are positioned correctly inside the hole as this would cause the heater to not fully sit inside when positioned incorrectly....

  • Troubleshooting No Hot Water On Tap With An Atwood RV Water Heater
  • If you're sure that your Atwood water heater # DMC74FR is actually heating up the water but you're not getting hot water at your faucets then you must have a shut off valve somewhere in line from the water heater to the faucets. If the water isn't actually heating up then the regulator is most likely the issue and needs to be replaced. In my personal opinion, since Atwood has been dissolved into Dometic I recommend replacing the water heater altogether with a tankless option like the...

  • Is There a Fix for the Kat's Heaters Handi-Heat Magnetic Heater Not Heating Up
  • The Kat's Heaters Handi-Heat Magnetic Heater # KH1155 thermostat kicks the heater off when it heats up the fluid to 275 degrees Fahrenheit. This means that it should be heating up right away when it's plugged in. If this is not the case the the unit is malfunctioning and I recommend taking advantage of the 1-Year warranty if applicable.

  • Troubleshooting an Atwood Water Heater with Dual Switch that Caused a Fire in the WH Junction Box
  • To be honest, I don't think it is an issue with your switch. More than likely it is a wiring issue. But, it could depend on what your water heater model is. Some models have 2 separate heating elements (gas and electric) and the switch controls which heating element is used. Other models the electric switch is the ignition and the gas is the fuel for the water heater to heat up, kind of like you mentioned thinking it worked. More than likely this is a wiring issue. Sometimes wiring vibrates...

  • Troubleshooting a Kat's Heaters Custom Fit Engine Block Heater # KH11484 Causes Outlet to Cut Out
  • If you have a Kat's Heaters Custom Fit Engine Block Heater # KH11484 that you referenced and it is causing the outlet of your vehicle to cut out then the problem is that the outlet is getting overdrawn either by the heater drawing too much amperage for the outlet to handle or because the heater has a short in the wiring of it and that's causing the outlet to short out. I would recommend you go over the wiring of the heater looking for any cuts or other obvious signs of a short as that...

  • Troubleshooting Fogatti Water Heater That Won't Stay on
  • The reason your Fogatti RV Tankless Water Heater # LSB64FR is not staying on may be due the unit not getting electricity, gas, and water. Or, it may also be due to a dirty filter. Ensure the filter has no debris in it, and if there is clean or replace your filter and check again. Finally, the problem may have to do with low water flow rate. Some tankless water heaters have a minimum flow rate requirement and if that number is not reached, then the heater will not turn on. So you can try...

  • Can 6 Gallon Hott Rod RV Water Heater Conversion Kit Be Used for 10 Gallon Water Heater Tank
  • If you're using the 6 Gallon Hott Rod RV Water Heater Conversion Kit # DGR6VP for a 10 Gallon application then that would mean you're overworking the kit which could, in turn, burn it up. For your 10 Gallon water heater I recommend using the 10 Gallon Hott Rod RV Water Heater Conversion Kit # DGR10VP instead.

  • Troubleshooting a Fogatti Water Heater That is Not Giving and Error Code But Keeps Shutting Down
  • When troubleshooting a Fogatti water heater like the Fogatti RV Tankless Water Heater # LSB64FR, according to the manual it "will" show the error code and sounds the alarm "beep, beep, beep". If your water heater is shutting down with no error code or beep, it sounds like you may have a power issue. You can open the door of the water heater and insure the switch inside the door is open and the fuse is intact. If the fuse has blown, you would want to replace the fuse with a fuse of the...

  • Recommended Replacement Water Heater For An Older Atwood Water Heater
  • To me that sounds like you have a bad regulator, and it should be replaced. Unfortunately, the replacement regulator for your water heater has been discontinued and because of this, the best case is to replace the entire water heater. I recommend checking out the: -Fogatti RV Tankless Water Heater - Gas - Automatic Pilot # LSB64FR for white, or, -Fogatti RV Tankless Water Heater - Gas - Automatic Pilot # LSB44FR for black. This water heater measures 14-3/8" long x 15" wide x 15" tall,...

  • Troubleshooting RV Water Heater With No Hot Water
  • Most of the more recent Atwood water heaters as well as other manufacturers us a plastic tank. The plastic tanks don't need the anode rod to keep the tank from corrosion. It sounds like you have a problem with the heating element since you don't have any hot water if you have an electric heater. I recommend checking your pilot and regulator if you have propane heater.

  • Will The Excel RV Tankless Water Heater # EX93FR Turn on Randomly When Not In Use?
  • The Excel RV Tankless Water Heater # EX93FR monitors water pressure to determine when it turns on. If it senses a change in the water pressure of 2psi it will begin to heat water. Depending on where you are located I know some campgrounds will experience a large pressure drop when multiple users are using the water. Since your heater senses pressure drop that would confuse this water heater.

  • Troubleshooting A DSI FLT Error On An RV Water Heater
  • The DSI FLT light just means that the water heater has tried to ignite and kick on and wasn't able to. This can be caused by low propane levels, a bad propane regulator, or a faulty water heater. I recommend first turning off the power running to the water heater, this should either be a fuse or a circuit breaker depending on the model you have. Next check the propane levels, if the tanks are full make sure the knob is fully open as well for the gas to flow. Try powering the water heater...

  • Fogatti Tankless Water Heater Troubleshooting
  • I spoke with Fogatti and the steps to troubleshoot your # LSB64FR issue are as follows: Any error codes? If so we can look through the manual to determine the solution. What is measured voltage at the water heater? If you're not receiving the required voltage it could allow the control panel to work but not have enough power to run the heater. You'll need 12VDC electrical power. Where is the unit grounded? If you're not properly grounded this could cause energy spikes that can damage...

  • Furrion Tankless Water Heater Installation Troubleshooting
  • It sounds like your Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU - 16" x 16" Door Item # FR98SR is getting too much voltage to it. Your prior gas/electric water heater was most likely taking 120V AC current. You can run a new wire to the battery or use an AC/DC power converter panel like the Progressive Dynamics RV Power Control Center with AC/DC Panel and Converter/Smart Charger - 60 Amp Item # PD4560K18LS8 to run the proper voltage to the new water heater.

  • Troubleshooting a Fogatti Tankless Water Heater That is Always Too Hot
  • The Fogatti RV Tankless Water Heater # LSB64FR does require the Camco RV Water Heater Temperature and Pressure Relief Valve # CAM10423 to be installed. The Camco RV Water Heater Temperature and Pressure Relief Valve # CAM10423 protects your RV's water heater from excessive temperature and water pressure. If this was not installed, that would be why your water heater is always too hot and you would want to have it installed.

  • Replacement Water Heater For Leaking Atwood GC10A-4E Water Heater
  • I know it's not ideal, but it sounds like the tank is leaking and that isn't something that is offered as a replacement part, so your only option would be a replacement unit. If you're just wanting to replace your unit with virtually the same unit, you can use the Fogatti RV Tankless Water Heater - Gas - Automatic Pilot # LSB44FR for black or # LSB64FR for white. This is similar to the water heater that you have now with a 41,800 Btu heating capacity, cut out dimensions of 13" wide x...

  • Atwood G6A-8E Water Heater Water Not Heating Up
  • There could be a number of reasons your Atwood G6A-8E water heater is not heating the water properly. It could be because: -The By-pass kit valves not set properly. What you'll want to do is put the valves in the proper position. The main purpose of the water heater bypass valve is that it prevents anti-freeze from going into the heater tank when winterizing your RV water lines, so this could be causing the issue you're having. -The thermostat is not seated properly against the tank....

  • Is Smoke the From the Kats Heaters Vehicle Heaters # KH24250 On First Use Normal
  • If it only smoked the first time you used the Kats Heaters Vehicle Heaters # KH24250 then you should be fine. If it continues to smoke after every time you plug it in that then something is wrong and I would recommend you remove it as it is malfunctioning. Most likely the heater had dust on it from packaging and now that it's been used once it won't smoke again.

  • Troubleshooting Atwood GC10A-4E Water Heater
  • It sounds like you have a lack of LP flow, check to see if the pilot light itself is lit; it should be. If your propane supply is good, full bottles and a functioning regulator, verify this by operation check of another LP appliance such as the stove. If the stove functions properly then your LP system is proper at least up to the point of the water heater. If your pilot light will not stay lit ensure there are no obstructions/blockage. You may have a bad thermostat/regulator in need...

  • RV Water Heater Will Not Light
  • It's difficult to say for sure what might be preventing your water heater from lighting, as there are several possibilities. The most common cause is a bad thermocouple. We do have a few replacements available such as the 18 inch # CAM09273. This is a universal-fit item. I have attached our available selection that you can also check out. If nothing is happening when you flip the switch then you may just need to replace the switch itself. We have a replacement with part # AT91959. If you...
