Generac Generator Troubleshooting Generac generator troubleshooting guide. Top five reasons why your Generac generator doesn't work and how to troubleshoot. Troubleshooting Tips The first thing I recommend, before you start working on troubleshooting a Generac generator is to read the manual thoroughly. The manual cover directions how properly to install the unit, safely operate and handle the unit, and much more. The manual will also show you how to avoid situations such as electrical, fire and explosion hazards. Be familiar with the generator components, explore the pictures, features and the specs.

Generac Power Systems supplies their Engine Shutdown Add-On Kit to bring Generac standby generators into compliance with NEC article 445.18(B). Installation may require a controller firmware update. For example, a 50 hp Code F motor requires 279.5 LRKVA per horsepower upon starting (50 hp x 5.59 LRKVA per hp = 279.5 LRKVA/hp). LRKVA is also known as “starting KVA” or “SKVA.” Small motors have a higher NEMA code letter and correspondingly higher LRKVA-per-horsepower requirement than large motors.

Proper installation and regular maintenance are very important for reliable and safe generator work. And this is where the root cause for possible problems is. Generac generator troubleshooting words of caution • The national code requires you properly to ground the generator. • Connect the generator per manual guide. The best way to connect the electrical loads is by using the transfer switch. • Use the electrical loads per specs. • Let the engine run for few minutes after starting so it can stabilize and warm up. • Do not overfill the fuel tank as it might get into the hot engine and cause fire or explosion. • Do not overload the unit as it may harm the generator and connected electrical devices. • Never operate the generator inside and near open windows. • Never start or stop the generator engine with the electrical devices plugged in and turned on. • Always disconnect the spark plug wire so it cannot contact the spark plug, as it might accidentally start the unit. • Unplug the unit before fixing it. Generac generator is equipped with the safety features, such as the Low Oil Level shutdown system, that shuts the generator down if the oil level drops below the specified level. In this case, there is nothing wrong with your unit, you just have to add the oil to the proper level. Regular maintenance for longer life Generac generator troubleshooting guide also recommends the maintenance, again for the proper work and longer life of the unit. Oil check should be performed often, basically after every use, together with cleaning the dust and dirt. At least once a year perform the recommended maintenance such as changing the oil, replacing the spark plug and air filter, or more frequent when operating the unit under the heavy loads and in dirty, humid and high temperature areas. In addition, valve clearance should be kept per specs and adjust if necessary. If not planning to use the generator for a month, avoid problems by removing all gasoline from the fuel tank. Try to run the generator once every week, at least half hour. Generac generator troubleshooting problems Problem 1 - Engine won't start If you have a problem with the generator so the engine won't start, or it runs rough, and you want properly to troubleshoot and repair, here are the cause and solutions: • Check do you still have a gasoline in the tank. You know what to do, but first make sure the engine is not hot. • Replace the spark plug if it is bad. • If there is water in gasoline or gasoline is stale (usually happens after 30 days or more), drain the fuel tank and replace it with the fresh gas. • Install the spark plug properly if the connection between the spark plug and the wire is too loose. • Check is the shut-off valve in ON position. • Is the fuel line blocked? • Clean or replace the air filter if it is dirty or bad. • If the engine is over choking, put the choke knob to NO CHOKE position. • If for any reason, the engine had lost compression or valve is stuck open or closed, call the qualified technician. Problem 2 - Engine shuts down Generac generator troubleshooting when the engine shuts down during the operation. The worst it can happen, is if the generator engine needs to be serviced. If that is the case, you have to call a technician. Kompres foto jpg ke pdf. But, before you do that, check if the generator had run out of gasoline, or the oil level is low. Problem 3 - Not enough power The engine doesn't provide enough power. Again, the serious problem is when the engine needs to be serviced, while if the load is too high, or you have a dirty air filter are very simple problems to work on. It is very important that the total wattage of all electrical devices should not be greater than the generator's wattage capacity. Problem 4 - No AC Generac generator troubleshooting is also simple in a case if the engine is running but doesn't generate AC. • Reset the circuit breaker if it is open. ![]() • If the connected device is bad use one which works. • Check to see is the cord set poorly connected or maybe defective. • If the problem is with the unit call the customer service for repair. Problem 5 - Engine slows down If you have a situation where the generator's engine is running good, but it slows down when you connect the load this is what might be the reason and solution: • Your generator is overloaded. • Disconnect the shorted electric load. • Check with the technician why the engine is running slow. Generac generator troubleshooting guide with five examples from the above does not apply only on one model, but on other as well. According to manufacturer, most four stroke generators have problems, which are related to two of the above 5 problems; engine won't start and engine runs poorly. Related articles • • • • • • •. Original review: Jan. 4, 2019 The first power failure the generator came on fine. The next one it failed to come on and locked up. It gave error code E1062. The dealer reset the unit and the next power failure it did the same thing. The dealer said he could not fix and I had to get another dealer to do the warranty work. Two separate dealers have given me the runaround and they all are too busy to set an appointment. Generac customer service says I have to call a dealer. The unit is useless as is Generac service. DO NOT BUY A GENERAC UNIT and especially not the Synergy unit. Original review: Dec. 28, 2018 Bought the 16 kW home standby generator in 2004 because we have a lot of power outages in living rural. Generator ran okay for several years. Had an over-speed trip problem, battery charging problem. Generac tech repaired those at my costs. Had a slow starting problem (still do). Generac service companies (2) cannot fix it. One service company charged me $356. For the service call, 2 spark plugs, one air filter and it didn't help any at all. Had another tripping off problem. Generac tech said it was a bad stator. I replaced the rotor & stator for $1300. Original review: Dec. 22, 2018 This unit is brand new and has never run. Zero hours on this units clock. I have called the Generac company three times but have not been helped or given advice on how to fix this problem. The problem is I can not move the fuel selection switch from natural gas to propane. I was told there is a pin stopping the switch from turning. There are several Generac service people in New Hampshire but the few I called never returned my call. Generac never returned my calls or offered to help with this problem with the fuel selection switch, keeping in mind this unit is brand new and never has run at all. Original review: Dec. 11, 2018 I purchased the Generac EcoGen in July 2015. Home is off grid and Generac had a good sales pitch. The EcoGen was hooked up and activated on Sept 15, 2015. It would not start so service was ordered. Generac repairman walked into my yard looked at the EcoGen saying he knew nothing about them and left. Second repair call was two weeks after. He diagnosed issue as the main motherboard. An additional two more weeks for part to arrive and two more weeks to installation. Generac has it finally turning on Nov 30, 2015. We were building our home so usage began Nov 2017. Now on Nov 16, 2018 it shuts down during dinner and will not work. Contacted Generac Nov 17, 2018. Today is Dec 10, 2018 and so far NO Generac repairman has been to my home. Generac one day says generator is not under warranty then two weeks later says it is and now today says no warranty. The whole issue is when DID my warranty start? When it was activated or when Generac got it running. This is all documented with Generac, yet they are choosing to ignore. We are very disappointed with Service and support from Generac. We also found out that Generac has discontinued this generator due to the number of problems associated with it. AND Generac knew there were such issues and didn't do a recall. Activate Generac GeneratorAND now they are putting this burden on the customer who paid for this device. Generator less than 200 hrs; cost $3900; repair quote $3,000! Original review: Dec. 2, 2018 I had a 20 KW Generac Synergy model installed this summer (June 2018). I chose the Synergy model after reading that it would be quieter running and save fuel due to the capability of varying the running speed due to the load required. Generac Startup CodeI live in Central Virginia about 40 miles southwest of Richmond. We lost power for the first time during Hurricane Michael for four days (90 hours) and it never missed a beat. I was without power for 5 seconds while the transfer switch turned power on from the generator and that was it. A few weeks later the power was out for about 8 hours. Again, after 5 seconds my generator supplied my power needs flawlessly.
