Question about Air Conditioners

2 Answers

My oil boiler is a Danesmoor SLPJ 20-25 with an Electro Oil Inter 2011 burner. The oil tank ran out and after refilling the burner ran ok for approximately 6 minutes, the control box chattered and the boiler sound indicated flame out, with the blower continuing then re ignition, flame out, re ignition, flame out and then lockout. Considering restriction / air lock in fuel line, the tank filter was changed, pump filter was cleaned and fire valve was cleaned out which was giving a gunge restriction. Fuel flowed freely into a bucket at connection to burner. The problem is still exactly the same with an approximately 6 minute run, flame out, re ignition, flame out to lockout. Any ideas, Keith

The actual final solution was to replace the fuel valve/solenoid following which the boiler has run without failure.
The conclusion was that the fuel valve solenoid was ok when cold but when heated up had some sort of electrical breakdown in its coils, causing the fuel valve to fluctuate until the boiler locked out.

You could have a problem with a temperature sensor.
it would not be the flame sensor since it could not wait 6 mins to sense that there is flame in the unit.
could be a temperature sensor problem where it is sensing a temperature which could be correct but it is sending a wrong signal to the controller to turn off the flame and start another cycle.

The cover on my oil tank for the heating got blown off and rained heavily for a couple of days and water got inside how can i separate the water from the oil


There are treatments (chemical) available, depending on the amount of water in the fuel. BTW, the caps on those tanks just don't blow off, they're treaded and screwed on ( I know this because I delivered fuel oil for 8 years).

My oil boiler keeps locking out


turn off the power to the system and then open up the transformer using a 5/16 nut driver. The transformer is hinged and it will flip out of the way. Look for a small black cylinder with yellow wires. Clean off the eye. Then turn off your oil supply to the burner. Using a 7/16 wrench, unscrew the very small copper line at the end where it enters into the burner housing, then spin off the round nut holding the drawer assembly. Rotate the drawer assembly and pull it out. Inspect the nozzle for soot and replace. The size and angle of spray will be marked on the side of it. Inspect and adjust your electrodes according to the manufactures specifications of the burner (not the boiler). Put everything back together and test fire it. If your boiler has not been cleaned in the last year, change the filter at the oil tank. If it continues to lock-out, change the primary control (usually honeywell 8184G) with a newer version.

Ran out of oil, now refilled, but boiler won't ignite. Tried all as owners manual instructs, but still keeps locking out - help please


After running out of fuel,you need to bleed the oil pump on your burner.There should be a 3/8 bleed port on the bottom of your burner pump. The bleeder valve looks like a nipple. A 3/8 opened end will fit over it.Put a can or cup under it,open it a bit and reset your control.when pure oil comes out close it and burner will fire.If your not good with it you should get a tech or handy man to do it.

Potterton statesman oil central heating boiler the household oil ran out and i had it refilled and now the lock out button is illuminated i believe i have to press the burner reset button but not sure...


Hello my name is Heath it will be my pleasure to assist you. You will have to push and hold the reset in on the side of the control for 15 seconds. But you will also have to bleed the air from the system from the 3/8 nipple on the lower left side once the lockout has been released and the motor starts.

Fuel oil level extremely low: possible problems?


After your fuel tank is refilled let it set if possible for solids to settle. In the line near the tank is a fuel filter. This fuel filter should be changed regularly, normally annually. The air must be vented from the fuel filter though vent screws located on top of fuel filter. Do not remove the screws completely as air will vent as they are loosened. At the burner oil pump is a vent to which you can slip on a 1/4 inch hose and direct into a container. On burner start up loosen the vent at the oil pump and observe oil going into container. When solid stream of oil is seen close the vent. The vent looks like a grease fitting on an auto.

follow these instructions: One problem that can occur is the nozzle for the burner sometimes becomes plugged if solid particles make their way to it under low oil conditions. If this becomes the case you should have a heating service tech change the nozzle and fuel filter. However try the venting procedure first. You just may be O.K.

Domestic oil fired central heating. Keeps tripping out with no oil feed(has tiger loop and this is empty) If oil is drawn through filling tiger loop again boiler will fire up and run for betweeen 2 days...


many times the feeder tube from the bottom of the tank becomes perforated. the return tube is ok most of the time . try switching the 3 8 tubes from inlet to outlet and see if problem resolved. if so the the tube down into the tank is flawed.
