Furnace blinks seven times lockout do to retries will light up for 5 second then it turn off

7 blinks means unit is locked out it will stay locked out for one hour then try to light again it will try two times before lock out. Possible causes. Low gas pressure, Faulty gas valve, Faulty hot surface ignition or burner problem may cause this. Most common is Hot surface igniter.

The clean filter light is flashing on my Bowin SLE2 however the only filter i can see at the back is dust free? Where else might there be a filter?

It should take just a min to remove it and vacuum it. If it will start with the filter out try and see if the light still blinks

After it has been on for a while the filter light start flashing. Tell you tell me why please. It has just been serviced.

Ben, just because the heater was recently service, doesn't mean the filter may have gotten dirty from use, since then. Or the filter was overlooked during servicing.

In either case, turn the electrical part of the heater OFF and unplug it from the wall receptacle. Remove the filter and clean it, if necessary. Reinstall the filter properly, plug the unit back in and turn the Master ON/OFF switch to ON. Start the heater and the Filter Clean Light should not glow.

Hope this helped you solve the problem.

Been sitting for a while, filled with fuel, turn on runs for 5-10 secs then shuts off and light blinks ?? model 3ve51

You need to pull a little maintenance on this unit. Locate and remove the burner tray, on the tray you will find a flame sensor, this detects flame and permits the unit to run. These collect carbon deposits, dirt and the occasional insect seeking shelter. So clean it with windex and a soft terry cloth rag. Next is the fuel nozzle, find it , remove it, and they say you can not clean these but I say q-tips, tooth pick and carb cleaner will do the trick just be careful not to damage the nozzle. Directly behind the nozzle is a screen these like to corrode durring storage, so clean it good too. Put assembly back together and inspect all fuel lines for holes, leaks,or dry rotten conditions. Now inspect fuel lines to the filter, if an in line filter (small plastic filter) clean with compressed air and blow gun, blow air backwards thru the filter instantly cleaned. If a large oil type filter replace it with a new one and do not forget to fill the filter before putting it on.Make sure that your fuel is clean and no water has developed in it from condensation, if water is present drain fuel and clean out the tank put new fuel in and it should now work for you. Happy heating

My goodman furnace light blinks 4times

OK you could have a plugged air filter, the limit switch could have blown or the room air blower is not working. Clean or replace the air filter. Make sure all wire connections are tight. If it still does not operate, you will need to call your technician.

Filter light & water mark

The tray is if you want to add humidity. You will constantly be filling it. The filter light could indicate a dirty blower or debris slowing down air flow over the heater.
