I just purchased a 2000 CC Magna from an individual and am having problems with the propane system. I attempted to start the refrigerator and run it on LP but it failed to work. The refer works well on 110v. When I first turned on the LP alarm so the solenoid valve on the tank would open it chirped continuously. Since the coach is 10 years old I assumed the alarm was bad and past its expiration date anyway.

I replaced the CCI # 7719 alarm with a Sat-T-Alert 30 Series Clasic LP Gas Alarm. According to the package label and the RV parts store, this is a direct replacement for the CCI. Although this new alarm has no on/off switch like the CCI, when I connected it, the LED came on and turned green. While I was replacing the alarm, I tested the voltage to the alarm and it was above 12 volts. Although the CCI is a 3 wire alarm, while the new alarm is a two wire alarm, the two red wires on the CCI alarm are joined together and connected to the hot lead from the coach.

I'm still getting no propane to the stove and I assume the refer since it won't work on LP. I've checked the wires at the solenoid with a test light and it failed to light. I've looked through the wiring diagrams in my owner's manual and can find nothing on the lp alarm and lp tank solenoid.

Does anyone have any tips that may help me with this problem?

If you have a solenoid on your tank... Take it back.. Only the model 70 series

70 Series – Dual Propane/LP and Carbon Monoxide Alarm

Has the relay to turn the LP solenoid on and off.

Thanks Rick. I'll be making a return trip to my dealer.

Had a similar problem with getting propane to my stove as we have a residential fridge. It turned out to be the solenoid just past the regulator on the propane tank. That company is out of business, but RV tech was able to find one still and replaced it and all is good with that. One problem solved. If he did not find that solenoid was going to have to replace the system which included a new detector and new solenoid, about $250. While he was looking for one he bypassed the solenoid, only thing is if there was a leak and the alarm sounded it would not shut off the propane.

We started ours, was new to us coach that had been stored for some time.

It must have too 5 minutes to purge the air out of the lines before the stove would start.

Measure the voltage at the selenoid to see if the alarm is giving positive control, if voltage present the selenoid may be bad, or the piping full of air.

If you are thinking about changing the selenoid anyway, loosen the pipe PAST the selenoid, turn off the tank valve and on the alarm.

Confirm voltage at selenoid, then slowly turn on tank valve, if you hear gas then turn off tank and tighten pipe, selenoid is fine.
