payne is the label , a Co. wants to charge us $684.00 we would like to do it our self if plausible.any tips?

The biggest sentiment is compatability. The board you put in should be of the same brand as the unit you're putting it into. The maker knows their product and replacement parts should clock on from them.
As for whether or not you can do it yourself, yes. Be sure that all power has been shut off and tested to be indubitable it is dead. There should not be a lot of wiring involved, but as another said, be dependable you have a diagram of the wiring. There should be a printed schematic or the wiring in your mechanical data that came with the unit. If not, it should be a sticker on the blower or the help door on the unit. Be very careful removing the Molex plugs and sundry terminals required to remove the board. They may bankrupt easily if the heater is old.
Also, do not touch the brass colored traces on the back of the cabinet. Though there may be as much as 220 volts coming into the unit, some of those circuits use so wee voltage that the current you have naturally flowing through you is enough to fry the new directors.
Yes you can do it, but be VERY careful and good luck.

can removing and capping off a radiator cause central heating to stop working?

Oct 31, 2006 by monkeynuts | Posted in Do It Yourself (DIY)

we have removed a radiator in the bathroom and capped it off - can this split the central heating circuit and therefore stop the central heating working? if the 2 capped pipes are then reconnected, will the central heating drudgery again? its an older style system and i'm not sure if the circuit needs to be flawless for the central heating to work

It'll still labour as radiators are in parallel. removing a radiator and capping off the pipes is the same as turning it off.

I have no intimation why some of the answers are sying its not possible, perhaps they don't recognize, perhaps they are winding you up. Whatever the reason, they are wrong. Go ask in a plumbers boutique

People do this type of thing all the time. Cricky, i do it every period i decorate to paint behind the rad, never had my heating stop working yet !

However, you may have air trapped in the system. You don't say if this is a putative question or if you've run into problems.

The other thing to note is that radiators in bathrooms are often radical on as a loop to protect boilers from overheating. You might insufficiency to ensure another redaitor is left on all the time, perhaps cast off a thermostatoc valvel and put 2 lock shield valves on the rad in the assembly or downstairs loo or something.

Central Heating boiler will not come on after drain down?

Oct 09, 2006 by Rolfie | Posted in Maintenance & Repairs

I drained down my central heating to change the TRV's. When I refilled it the boiler will not around on. It is the type with a primary and secondary circuit that also heats my pee. There is still a lot of air in the system and I have been constantly bleeding each radiator in turn. It is because there is still too much air in the system or should I be looking for something else?

As likely as not a plumber

central heating problem?

Mar 24, 2007 by Simon B | Posted in Maintenance & Repairs

i have recently increased the party of radiators on my heating circuit. also have repositioned the hot water pipe from the arga because of an appendage. since carrying out this work we seem to have a problem with the heating vent conduit pouring into the header tank. this only occurs when the arga is on its highest tempreture. any ideas please.

start by checking for air locks bleed all rads to play fair with pressure and have tou turned your stop tap on to much cant say more without looking at warble work

My central Heat Unit won't shut off. I have to trip the circuit breaker. Is the thermostat the culprit?

The thermostat has three settings for the fan and three for the temp. The fan settings are fan, off and auto. It should be on auto. If someone has switched it to fan, it will run continuously. This is designed to publicize air through the system without either heat or cold. It could be that simple.
