    What is it set on?



    how are you trying to get it into defrost mode?



    Are you forcing it to frost up so the sensor senses frost before attempting a forced defrost cycle?

There is typically a set of jumper pins on the defrost control board that allow the system to go into defrost after 30, 60, or 90 minutes of run time. There are also two bare pins that say "test" on them. While unit is running, approx 15 min or so in heat mode, short those two pins together for about 5 seconds, this will force the unit into defrost mode. If it still does not work, you might still have a defective board. Depending on the humidity in your area, that is how you determine the defrost interval.

I have a 9610 thermostat turns on and off to frequently


I am guessing but the thermostat is either faulty or is in conflict with another thermostatic device in the system. The room thermostat measures the air temperature in the room but with a modern intelligent boiler there will be other sensors measuring all sorts of things including the water temperature.

Personally I prefer to have thermostatic radiator valves rather than a room or zone thermostat.

My thermostat is set on 68 degrees and it shows room temperature is 68, but the furnace still kickson, Honeywell said it has a 1 degree difference. so what's the problem then?


Yes there is a one degree tolerance, in fact my heater just kicked on and it is set to 67 and the inside temperature reads 67. It is also a Honeywell.

Kenwood Electric Oil Heater. Model EW7507EK. Can anyone tell me what color order of wires onto the circuit board? I feel like an silly for not taking a photo before starting the repair. F3-5


Look carefully on the board itself. Sometimes the wire color codes are labeled right next to the connector. If not, there may be some other letter codes and these should match the ones on the thermostat.

Johnson Starley boiler main board fuse blowing


Chances are the fuse on the circuit board is for control circuit protection. Take note of the location of all the thermostat connections on the circuit board and remove them. Do this with the power OFF. Replace the fuse and re establish power. If the fuse did not blow, the problem is in the wiring to or from the thermostat. It could even have the insulation rubbed through and making contact with the side of the boiler or a mouse could have chewed through the insulation causing a short to a metal object.

Once the issue with the thermostat wiring is resolved, reinstall the low voltage connections and you should be good to go.
