The documents can be filled in online and then printed. To receive an RGA number, email the completed documents along with the Proof of Purchase to the email address on the form. If you need an immediate replacement, complete the “Credit Card Authorization” and fax that with the rest of your forms. Authorizations received before noon EST will be sent out that day.
For Dealers and Retail Customers. During the first year, manufacturers (OEMs) typically cover the warranty. If not, please contact the WFCO Power Pros at 877-294-8997, Option 1. Troubleshoot your unit with the Power Pros before filing any warranty claim. Should you need to return a product, please follow the procedure in “How do I file a warranty claim” above.
No. If the unit is within the 2-Year Limited Warranty, you may submit it for warranty consideration by following the "How do I file a warranty claim" procedure above. If warranty is approved, a replacement unit will be issued with warranty valid for the remainder of the original 2-Year Limited Warranty term.
(Replace with an ATO or ATC fuse having same rating as the original.)

Before you call the Power Pros check the following:
1. Locate and record the WFCO converter model number.
2. Are you connected to shore power?
3. Check breakers at the pedestal and in the power center for proper voltage.
4. Are all of the fuses on the DC panel OK? Are any red LED’s on?
5. What is your battery condition? Does it have enough water? What is the age? Have you tested for shorted cells?
Voltage Check:
1. Disconnect the Positive lead at the battery terminals and set aside.
2. Turn off all DC loads in the RV.
3. Are you reading 13.6 VDC between the Positive battery lead and the Negative battery terminal? If not, the Reverse Polarity fuses may be blown at the converter or there is an OPEN fuse or battery disconnect switch in the Positive battery lead.
4. Any battery reading below 12 VDC while disconnected is a possible indication of battery trouble.
If you have no AC power, check the following:
1. Are you connected to AC power at the pedestal?
2. Is your Main Breaker tripped?
3. Check your wiring for any problems.
To determine whether or not the converter is bad, call the WFCO Power PROs at 877-294-8997 and a technician will troubleshoot the unit with you.
If you have no DC power, check the following:
1. Is AC power coming into your RV?
2. Is the converter breaker in the ON position?
3. Are the Reverse Polarity fuses in good condition?
4. Check your wiring for any problems.
To determine whether or not the converter is bad, call the WFCO Power PROs at 877-294-8997 and a technician will troubleshoot the unit with you.
1. Remove some of the load by turning off 12V lights and appliances.
2. Turn off the converter for 10 seconds to allow the unit to discharge by either turning off the breaker or unplugging the unit.
3. Turn the converter back on.
4. Check the output voltage of the converter. It should be approximately 13.6 VDC.
5. Check your battery. It might be damaged or the water level may be low.
Keep in mind that your battery can pull up to 30A or more from the converter. Low temperatures also will have major effect on your battery's performance.
If the lights in the RV are flickering, that usually means that the converter is overloaded.
1. Remove some of the load by turning off 12V lights and appliances.
2. Turn off the converter for 10 seconds to allow the unit to discharge by either turning off the breaker or unplugging the unit.
3. Turn the converter back on.
4. Check your battery. It might be damaged or the water level may be low.
5. Check the output voltage of the converter. It should be at 13.6 VDC range.
Keep in mind that your battery can pull up to 30A or more from the converter. Low temperatures also will have major effect on your battery's performance.
- Using a bigger battery bank can cause longer charge times. Having the correct-sized model converter will help with shorter charging times.
Call our Power Pros for more information.
-Turning off lights or other 12-volt appliances will increase the charge current to the battery.
the converter and the battery, the larger the wire size that should be connected. The longer wire distance, size, and length will determine the voltage drop. Charts are online to help with wire size, distance, and voltage drop.
Before you call the Power Pros check the following:
1. With lead acid batteries, be sure to check water levels.
2. Don’t use electrolyte (battery acid) to top off your battery levels. Use recommended distilled water after a full charge.
3. Don’t mix battery types or old batteries with new batteries. Using an old battery with a new one can damage the new battery if left in storage unattended for a period of time.
4. If your battery feels hot to the touch, have your battery connections checked or have your batteries checked by a trained technician.
5. If your battery is a lithium battery, make sure you discharge enough battery capacity to allow your WFCO converter to go into charge mode. This is part of the Auto Detection process to determine the correct battery profile for charging by the correct battery type.
6. Make sure your battery bank capacity is manageable for the converter charger. A larger converter charger is available for bigger battery banks. A smaller converter charger may take longer to charge.
- Example: 400-amp hour capacity battery bank with a WF-8725-AD unit. Suppose we were using the full 80 percent capacity of the battery
(this will be different for each battery manufacturer). In that case, it means out of a 100-amp hour battery, 80 percent is usable capacity, so charging at 25-amp hours, you will have just over three hours of charge time per battery. While the WF-8725-AD converter will charge a 400-amp hour battery bank, consider upgrading the wire size and a converter size to a bigger charge output to maintain optimum
efficiency when charging from a generator.
7. Make sure you have the proper fuse size to match the wire size gauge and insulation type of wire. Also, match wire size to the output of the converter. Wire size should handle the current rating of the converter and the distance from the converter. Various wire charts on the internet will help explain distance, insulation rating, and distance for multiple voltages and current ratings.
1. Check your AC breakers at the service box where you plug in for service for your RV.
2. Check your breaker at the Power Center or Distribution panel for tripped breakers. Turn off the main breaker and turn it back on. Check the rest of the breakers in your distribution panel or power center and do the same procedure.
3. If breakers are ok and don’t appear to be tripped, check for loose wire connections. *(Do this with AC power and batteries disconnected
from the system). *If you feel unfamiliar with the terminology or touching electrical equipment, you should schedule with your local RV technician for further assistance.
1. Check your connection to AC service.
2. Check AC breakers to make sure they did not trip.
3. Check fuses for continuity with aa continuity checker. Some volt meters will have this built in or listed in the selection range for the volt meter.
4. Check DC wiring for loose connections. The most common is a missing ground wire connection. Another is positive wire insulation being caught between the screw and the buss bar and not contacting the copper of the wire surface with the screw or buss bar.
1. If you have 13.6 V DC at the batteries, this is the absorb voltage for lead acid series batteries and the power mode voltage for lithium batteries.
2. Lead acid batteries will continue to charge at the absorb mode at 13.6 V DC and charge at a slower rate. *State of charge (SOC) will determine the number of amps going to the battery.
3. Lithium batteries at 13.6 V DC is the power mode voltage and are usually fully charged at this point.
4. Check In-line fuses. There are multiple in-line fuses. The most common are auto reset fuses. Most are thermal active types of fuses. These fuses are located within 18 inches on the battery positive side coming from the battery to the converter. A volt meter will be necessary to check if it is a bad connection.
