Im working on a 2 ton Mits P series R-22 its around 8 years old. I am getting a P6 code.
Unit is cycling of frost prevention. I was wondering gernerally speaking what the pressure is on the condensate or two phase line should be trying to determine if I have a restriction in the evap or the condenser.
Thanks in advance.
p6 usually refers to blocked air filter,faulty indoor fan
Both filters and fan work OK.
usually 48psig suction for a unit that age are the indoor coils clean,normally they get full of crap,-im sending u a manual via e mail
P6 = indoor coil frost protection in cooling or indoor coil overheat protection in heating.
Cooling
One of the 2 indoor coil sensors reads minus 15 deg C for 3 mins.
Heating
One of the indoor coil sensors reads over 70 deg C.
Possibly faulty indoor coil sensor or gas charge,providing everything is clean.
