I am on my second englander pellet stove in two weeks. The first was constantly shutting down on vacuum loss, and after calling their customer service and never getting hold of anybody, we returned it to lowes and got a new one. After hooking this one up we get the same error message. Has anyone experienced this amount of frustration with this error code on this stove? I am at a loss with what to do at this point, as I have tried every single thing I can think of...thanks in advance.
I'm having the exact same issue. New stove from Lowes. A Englander 55-SHPCB120. Runs through the start-up cycle without a hitch. But gives the "Loss of vacuum shutting down" roughly 12 minutes (give or take) in to the cycle.
I'm at a loss. Here's what I've done and know:
1. The printed date above the serial number on the back of the stove is: 11/18
2. My 3" Duravent flue is in this sequence: Appliance adapter, T-clean-out, up three feet straight, 45-elbow, up 1 foot left, 90-elbow, through the wall straight (1 foot), vent terminal Note: During start-up sequence I have very good venting. The pipe warms quickly after there is a good flame and I can feel a strong exhaust exiting at the terminal outside.
3. I've tried automatic mode and manual modes (M1, M5, M9). All roughly follow this time frame: 4 to 5 minutes I see live embers from the pellets, 7 minutes (give or take) a flame starts and continues to grow stronger. At roughly 12- minutes the exhaust blower seems to hesitate, the flame diminishes and several seconds later the "Loss of vacuum" message appears and the stove shuts down.
4. I've cleaned the vacuum port (right of the burner pot) with toothpick (No luck)
5. I checked the vacuum hose from burn chamber to vacuum switch. Added a clamp to one end that was missing a clamp. (No luck)
6. Re-seated the connections on the control panel. Just in case there was a loose fitting. (No luck)
7. Ran the diagnostics and all component tested good--including the open-door vacuum test, etc.
8. Isolated the vacuum switch and jumpered the two leads to give a false "good" vacuum signal to the control board and SUCCESS! The stove ran normally through the startup. Had the little (what appears to be) exhaust blower hiccup at about 12 minutes. But continued to run quite well till I shut it down at 30 minutes.
I can't run the stove with the vacuum jumpered. (not safe!)
I would think it odd that the vacuum switch could be bad on a new stove. Something is clearly up regarding the vacuum. I don't think it is an over temp since that is not the error message and it errors always at the same point in the cycle. And I wouldn't think it would continue to run normally even with the vacuum switch bypassed.
This is my first pellet stove so don't know what is normal. Does the exhaust blower change speeds when switching from startup to normal run mode.
Thanks in advance.
