Cfh is not an error code. it stands for "call for heat". back wash the pool filter. check continuity of pressure switch to ensure it is closing at proper pressure. jump pressure switch and if heater fires, there lies your problem

CFH means "Call For Heat", and SPK is "Spark". It sounds like you are running out of gas.Propane tanks need to have 30% in the tank for a heater to run correctly,and after they are filled you must bleed the air out of the line.If you have Natural gas,the gas line may be too small to supply enough gas to keep it running. NOTE...gas pressure MUST be checked with the heater running.

Why do I get CFH but then no SPK?


CFH = Call For Heat
SPK = Ignitor is Sparking - attempting to ignite raw fuel

In a lot of cases, Pressure Switch opens up, CFH , is cancelled and therefor no ignition sequence.
try cleaning filter really good. If cartridge, may be time for an overnight soak.

Dehumidifier Duracraft E1 error code on led display and red power light flashing. No action from unit.


HI.Error code 1 usually informs us that the filter needs cleaning.This might be needed qwhen the unit runs for 740 hours or more.So you need to manually clean the filter by removing firsst the cover then .you have to unscrew.remov e the filter located at the backmost part of the a/c unit.You can actually apply pressurized water to removed debris or apply detergent to soften hard debris.Thank you for choosing fixya.

What is CFH


CFH stands for "Call For Heat"
CFH means "Call for heat" and SPK means "Spark". They are status codes, not fault codes.
It basically means that the heater is turning on the heat mode and spark should appear shortly after the CFH code appears. At this point the heater should be igniting and the heater heating up.
If you are having a fault issue with the heater, please let us know if there is anything else that we can do for you!

I have model # p-m267a-nc-c it comes on I git error cfh then after a while i git hl2 and it wont heat after that. HELP Please TKS


"CFH" is Call for heat. That means your heater is trying to fire (not an error code). "HL2" is an error code which stands for "High limit #2". This error means the water in the heat exchanger is too hot,and the heater shuts itself down to prevent damage. Most common causes are poor water flow .Make sure the correct pump is running,and you have at least 10psi on the filter gauge. also be sure that the bypass valve is at least 1/2 way closed.The Bypass valve is located on the return line after the filter just passed the first tee.
